Yeah I know. I could try and sell is as "Hey guys, you are doing Silverstone National, Internation AND GP all in one season, isn't that great" - would that work :-)

At present the only other option appears to be Pembrey but we are waiting for BARC to conclude discussions with other clubs. We might get extra time at Snetterton so the problem goes away. I felt we needed to keep people informed of what was happening.

JohnB on 29 January 2020 at 10:04Link

Three visits to Silverstone in one Season. Are there any other options? 

*Cough* Croft :)

Steve Arnell on 29 January 2020 at 09:53Link

Round 6 – Race 13 & 14 – Snetterton 200 – August 29th

BARC have now advised us that we will be running on the Snetterton 200 (due to the 2CV 24hr race) for our visit in August. Therefore, based on the race schedule information, we are likely to be very heavily oversubscribed as the circuit limit for that configuration is just 38 cars.

We are discussing with BARC about getting more track time, however this will not be known for a couple of weeks. So, in order to ensure everyone has a Round 6 to compete in, we might have to split Round 6 into two separate meetings, with two classes racing at Snetterton on 29th August and the other two classes at another venue, possibly Silverstone International at the end of the season, on the weekend of 10th / 11th October.

Please bear this in mind when you are looking to book accommodation or testing at Snetterton. We are trying to confirm the situation and are looking to inform you by Monday 10th February.

Is there a photographer  for the Grad's series?   if yes, what are the contact details.

Attention all 135 Class Drivers!

Last year was the first year that we ran our own 'series' within the 135 class called the CTS Motorsport Newcomers Cup.

We plan to run it again for the 2020 season.  Aimed at novice, relatively inexperienced and the more experienced driver who hasn't ever been on the podium in their previous championship,  the idea is to give drivers an opportunity to race for trophies without having to be at the super sharp end.

With over 30 drivers registered for the 135 class this season, it looks like being a competitive grid..........the CTS Motorsport Newcomers Cup means there'll be more trophies up for grabs.

All you have to be is a CTS Motorspot customer to be eligible!  Whether you want full support, transport and storage or one of our emergency packages you'll automatically be entered!  Trophies top be  be awarded to the first 3 CTS customers in each round.

Feel free to contact me for more information or ask Adam Harrison about his experience in the Cup last season ;-)

Does anyone know a source for a replacement throttle cable inner for a Sigma Engine - Caterham spares sell the inner & outer for just under £70! 

I'd already cut the throttle pedal end nipple off and replaced with a clamp type so I could set the pedal position without having to compensate for the fixed cable length. 

My vernier measures the cable inner as Dia 1.8mm, Barrel End for throttle bottle connection is Dia 6 x 10 long. Cable length 1.5metres

Stephen Cottrell on 19 January 2020 at 22:03Link

Phil, there is a spare 12v feed under the dash that your v-box should connect to.  It's switched on and off with the fan switch to the left of the dash.

Give me a call if you need anything ;-)



Jon Curry on 19 January 2020 at 18:25Link

VBox Connection

I'm trying to wire a second hand VBox into my Sigmax and was hoping someone may be able to advise. The power cable for the device has a socket connector with 2 prongs on it. Under my dash, there is a compatible socket connector, but this one has 3 prongs on it (assuming +ve, -ve and earth?). Plugging it in and turning the ignition didn't work, so I've tried to diagnose with a multimeter.

Testing across the battery, I get just over 12V, so all good. If however I put one prong at the dash socket end (the one I'm trying to connect the device to), and one prong on the car battery earth terminal, I only get 0.8V reading which is clearly not enough to run the VBox.

A different VBox has been connected into this car once before, as one was fitted when I had some tuition last year, but I don't know exactly how it was done.

Does anyone have any suggestions?



Phil Clarke on 19 January 2020 at 15:52Link

I can confirm that impact sockets won’t fit but standard Halfords sockets fit perfectly.

Steve Arnell on 19 January 2020 at 14:13Link

Ian - should'nt do; my standard sockets seemed to fit OK

Gareth Cordey on 18 January 2020 at 12:49Link

A-Frame Fixings / Socket Access

Does anyone know if the A-Frame bolts (19mm) need a socket that is a special tool / turned down outside diameter? I've bought a set of thin walled impact wrench sockets and the 19mm socket is still too large to get onto the bolt head shrouded within pipe.

Stephen Cottrell on 17 January 2020 at 21:16Link

Hard-wired Camera Bulk Buy

Just a reminder that we have a bulk-buy organised with Innovv cameras for their fit-and-forget HD cameras - single camera kit £165, double kit £263.

I now have the single camera kit fitted to my car - very straightforward to fit and set up.

Wired cameras will be mandated from 2021, but why wait? If your GoPro-style camera fails to record (and they do, a lot) then you'll be looking at a fine from the Club (going to the Marshals Fund) which would have gone a fair way towards buying one of these kits.

Full details are in the December Newsletter, but note that the phone number there is incorrect. Call Steve Welham on 0330 2233108, and mention "Caterham Graduates" for the discount.

Already got a VBox? That will satisfy the wired-in requirement, but it needs to be set to record automatically. And the quality of video produced by these far exceeds the non-HD VBox recordings.

Happy to answer any questions about the cameras, or fitting them.


Roger Ford on 16 January 2020 at 20:02Link

Stephen, I would definitely add a (ready charged) battery to that list. 

Wheel nuts, and general nuts and bolts are always useful too. 

Harry Cramer on 14 January 2020 at 12:11Link


Unforeseen and unprecedented demand for membership this year means that the Club is taking the unusual step of closing membership this Wednesday. Thereafter we will be running a reserves list.

The decision to close membership is based on indications from members’ race schedules completed to date, which suggest that we may have issues accommodating all members that wish to race at some meetings.

We are currently working with BARC on increasing capacity at some venues, however, this is not guaranteed, given the limited availability of grid space this season.

We will be updating you once the remaining race schedules have been completed and we have concluded our discussions with BARC.

In the meantime, if you know of someone who wishes to join please advise them that membership closes this Wednesday.

Many thanks

Andrew Outterside on 13 January 2020 at 21:29Link

Looks like a decent list. I'd add uprights, and steering rack rod ends. Possibly a steering rack as well, though they're not cheap.

Oh, and could you let me know where you're parked up so I can come and plead with you if I need any of those bits ...

Roger on 13 January 2020 at 18:10Link

Trackside Spares

I'm making a shopping list of big bits that might be needed if/when my son decides to bend the car at a race weekend - As it's a dad & lad adventure/enterprise we're not planning on race support, so thought it wise to stock up on 1 off each frequently bent bits for a 310R/150:

Wide Track Front Wishbones Upper & Lower LH&RH

Wishbone Rod End

Exhaust Mount Bracket

Cycle Wing + Wing Stay LH/RH

Rear Wing


Nose Cone

Any advice on other common bits needed for your average caterham shunt would be appreciated.

Without having emergency track support is it wise or overkill to carry so many spares? I'm adept at fixing things with cable ties and gaffa tape, and don't mind begging if needs be, but are spares easily found at race weekends?



Stephen Cottrell on 10 January 2020 at 21:08Link

Happy New Year to everyone!  For those thinking about booking accommodation for Anglesey in June there are two rooms still available at the Cefn Dref B&B at Rosneiger LL64 5JH Tel 01407 810714 run by Derek and Gill Browne.  It is not cheap but a lovely location and only 5 miles from the circuit.  It was recommended by Kim and Jacquie Rayment so if you mention their name, mine and Peter and Di Marsh you may get a discount!  

Suzie Black on 05 January 2020 at 16:35Link

A few changes, then?

If they don't finish in time, can we hold a rallycross event?

Michael Downing on 04 January 2020 at 11:37Link

Zandvoort - this is what the track looked like on New Year's Day. The main changes are larger run-off areas, and banking at the Hugenholtz hairpin (3rd corner) and at Arie Luyendijk (final corner).

Mark Carter on 03 January 2020 at 17:08Link

You can do as Darren suggests if you have a way of keeping enough pressure in the fuel rail. Alternative way is just to have a fly lead that jumps from the battery positive to the fuel pump relay pin.

Charles on 31 December 2019 at 14:40Link

Do you have the connection on the fuel line (and just not the take off hose?) if so, you could borrow ours/someone else's for a one off (very handy to have though).

Don't split the line by hand - fuel will go everywhere and probably end up starting a fire.

I know some people have wired up to allow the pump to be run in isolation via a switch without the engine running .... but I just run the car up and let it go with an in line tap part-open to allow enough line pressure.

Darren Houldcroft on 31 December 2019 at 10:02Link

Thanks Darren - I saw the fuel take off /sampling point but I don't have a Quik connect and wasn't sure if I just loosened of the connector if id spray fuel everywhere - how do you operate the fuel pump once you have access to the fuel line - is it just key on/off to get the pump doing it's initial prime - or is there a way of getting it running  constantly to drain tank. thanks Stephen

Stephen Cottrell on 31 December 2019 at 09:41Link

Fuel burn rate for a 270 (135) is about 0.5/0.6 litres a minute (depending on circuit).... so possibly a little more than that? unless anyone says otherwise I'd go for say 0.7 l/min as a trial + a few litres in reserve and see what you have left at Silverstone?

P.S. If your gauge is anything like mine you'd be better of picking a number out of a hat to guess what fuel you actually had left ;) I use the fuel take off hose and drain down to be sure I'm getting it properly empty now if I need to 

Darren Houldcroft on 31 December 2019 at 03:36Link

Fuel Burn for a 150

Not sure of race length in 2020, but what’s a rough guide of fuel to allow for a race . I’m adding 30kg of lead ballast leaving 25.5 litres of fuel before coming in 3kg overweight, not sure how many race minutes 25 l.5 litres would cover? What capacity is a 150 tank, I syphoned  all I could swallow and 26 litre refill at the pump was overflowing... seems a bit small, would there be more fuel in there - gauge seems erratic but wasn’t showing empty, sort of 1/4 ish

Diff Refresh - As a novice running a 2014 310R / 150 this year, was thinking of doing LSD Diff Refresh myself, but have been advised to take to an expert as relatively inexpensive job - I'm planning on doing  removal  / re-install myself - any tips to guide me would be appreciated - Does De-Dion tube need loosening off / removing to aid removal? or can Diff squeeze past with only ARB removed.

Just looking at booking accommodation for Zandvoort and the NH is about €1000 for three nights with breakfast even for a NH Rewards Member!  So reserved the Palace Hotel with for €457.55 (including breakfast and taxes).  The Palace Hotel is on the sea front further down from the NH.  It is further away from the circuit but closer to the town.

Hi Andrew, Thanks for letting us know how the two and three race weekends are put together for costs, but l still think three races on a two day meeting would be more cost effective. You could have six race meetings rather than seven and still have the same amount of rounds. These are just my thoughts and I appreciate the hard work put in to arrange a calendar.                                                                                    Would there be any chance of getting an up to date list on who has already joined the club and in which class? Cheers

Malcolm Clark on 28 November 2019 at 16:56Link

Malcolm – it would be great if the cost of the extra track time was only £50 per car, however, it isn’t, and the Club is in effect subsidising the three race meetings this year. This is to provide variety (as requested by the members' survey) and to keep the entry cost below £500.

Another issue about having more 3 race meetings is that they would normally need to be over 2 days, and we’ve tried to mix things up with a selection of 1, 2 and 3 day meetings.

To attract new members, we have introduced the three meeting Trophy membership (taken up by three members to date) and the new Flex membership category.

Hope that helps.   

Andrew Outterside on 25 November 2019 at 20:45Link

Just a thought - I see a meeting with only 2 races (Excl Silverstone GP & Zandvoort) will cost a maximum £445 & a meeting with 3 races will cost max £495. Would it not be better to try and have 3 races as standard if all it is costing is an extra £50? Would this not entice new drivers into the club?

Dear All,

I just wanted to write a quick 'thank you' message to everyone. Winning the Championship was amazing and couldn't have been done without a lot of help from various individuals and Revolution Racing.

However being awarded the 'Drivers Driver' award was just the icing on the cake and both myself and my dad are immensely proud and grateful! Thank you so much for everyone who either nominated or voted for me, coming from the drivers, it is genuinely humbling. Thank you.

Thank you to everyone involved in the club, you have all been a great bunch and it has been a pleasure to have been able to spend the weekends at a track with you lot!

All the Best for 2020.

The seat issue (SeatGate?) is still an issue however as this will be a Caterham Motorsport lead event they will be taking centre stage on this. We will obviously be liaising with them and ensure that our views are know however their drivers have exactly the same issues as us ie. non-FIA seats.

This will be one of those "watch this space" things. I am not expecting any news on this until much much closer to June.

Hi All,

We’ve been working hard over the last couple of months to put together our 2020 calendar, which we hope you will like. Comprising some of the best circuits the UK has to offer, plus a “new” overseas GP circuit, we hope you’ll like it.

You asked us to provide a more varied format for racing, so in 2020 we have a mixture of 1 day and 2 day meetings along with our 3 day international event. We've even slipped in a couple of triple header rounds. Our Championship classes are also changing slightly as is our membership offering. For full details can be found here

There is more to tell you, but some things will wait for the Awards dinner at the Hellidon Lakes Hotel, Daventry. This will be held on the 16th November, so if you haven't already got tickets (book here), time is running out.

Caterham Graduates – PremierPower Race & Performance Engines – Engine Servicing

Hi Everyone,

Premier Power this year was nominated as a recognized engine supplierfor the Sigmax Championship.  We havehelped several customers this year with engine rebuilds or engine related workfor the series.  As nominated enginesuppliers, this means we are able to ensure engines are built to a levelplaying field and our rolling road sign off process has already proven enginesare leaving us with one or two horsepower of each other.  This is down to attention to detail duringthe build process ensuring cam timing is almost identical on each engine, valveclearances are set correctly and tight build tolerances are adhered too.  As part of the final build process, we alsofit seals to the engines which are to ensure the engines stay in the conditionthey left us, until scrutineers want to apply their own seals.


Just writing to let you know we offer a full range of services fromengine health checks to performance testing and cam belt changes.  For those of you that just want a healthcheck, we can carry out a borescope (view inside your cylinders without removingthe head), cylinder leakage test, valve clearance check and cam timingcheck.  This is a non-intrusive testwhich doesn’t check crankshaft bearing condition but apart from that gives youan idea of the condition of your engine.


Generally the Sigma is a great engine but as a weak point we have seenengines suffer problems with crankshaft bearings.   This isn’t through oil starvation but justbearings de-laminating which would lead to an engine failure if not dealt with.  Other than that pitted exhaust valve seatsand some wear in valve guides are other issues we have seen.  Customers reporting they have issues fillingtheir oil catch tanks with oil during races is also something we’ve heardabout, although this isn’t something we hear about once we’ve rebuilt theengine.


Caterham supply their engines we believe with synthetic oil.  Synthetic oil is engineered to reduce enginewear.  Engine wear is required to allowcomponents like piston rings to “bed in”. To run in one of our engines, we use running in oil and a rolling roadthat runs the engine, in the car through various drive cycles to load theengine and run the engine in.  Because aCaterham is a very light car, you would struggle to do this on the track or onthe road.  On the rolling road, the caris strapped done and loaded up so the engine can be put under heavier loads forlonger.  This doesn’t damage the engine,only allowing components to bed in properly. The net result is an engine that performs properly and that isn’tgenerating crankcase pressure due to leaking pistons rings and glazed cylinderbores.  


We also offer an exchange engine service, whereby we strip your engineand give you an estimate to rebuild it. We have engines on the shelf that have been completely rebuilt to ourhigh standards and that require running in. The price you pay is the cost to rebuild your engine, but what youreceive in this instance is an overhauled engine that’s ready for runningin.  So you get an engine back in areduced time than having to wait for yours to be rebuilt.  This service was aimed at helping customersduring the season although we are happy to offer this during the closed seasonif it helps.  Currently our exchangeengines just require dress items or Caterham parts to complete them.  These are usually removed, inspected and cleanedfrom your engine and then fitted to our engine before installation to your car.


As part of our rebuild service we also carry out an engine sign off onthe rolling road.  Once the engine is runin, we then perform a power test, giving you a power and torque curve for yourengines performance.  This will be loggedon our system and should you ever feel you’ve had an “off” result one weekendand doubt your engine, the car can simply be returned to the rolling road foranother test.  The result of this caneither result in a further health check of the engine, or as is often the case,focus your attention on another area of the car or your driving.


So you are a busy person who works hard during the week to earn moneyto go racing.  “When do I get time towork on my race car!!”.  Premier Poweroffer a complete service of engine removal, rebuild, re-install, transport andsupport to the rolling road and return to our workshop.  Customers who want to reduce their costs canwork with us if they wish by delivering the car to the rolling road themselvesand overseeing this part of the job. Should you require we can also store your car whilst it’s having workcarried out, we can offer to do this is our secure and fully insured facility.  If you want gearboxes, diffs or dampersremoving or any other car related work doing, we are happy to assist withthis.  We can also arrange collection anddelivery of your race car if required.


So why am I writing this now? We are now heading into our busy period and I want to make sure yourrequirements for the new season are met. Our order book is starting to get busy and I don’t want customersleaving it until February or March before they realize the 2020 season is uponus.


For your 2020 requirements please call Stuart on 07712 530858 or  We look forward to hearing from you J.


Thank you for taking the time to read this thread.

Final call for dinner footage - I have 45 clips laid down and 2 spaces left. Please send me what you have ASAP! A couple of showstoppers for the end would be particularly welcome. 

Charles on 19 October 2019 at 09:32Link

Just remind all those attending the Awards Dinner on the 16th November I need your menu choices by 23rd October. Many thanks.

Julie Clark on 18 October 2019 at 19:55Link

MORE dinner footage needed! - with only a month to go until the dinner it's time to start cutting and splicing the video. Many thanks to those that have sent in footage but I NEED MORE! Any exciting moments are welcome, in or out of the car. I'm in particular need of a couple of <cough> big crashes. So please, search through those SD cards and send me more stuff! For larger clips I suggest you use WeTransfer - just email me if you need more info on how to use it.

Your are quiet correct (I appear to be having a bad day). As Trevor came third the MCF does indeed belong to Robert. Apologies for that.

Here are my Cadwell photos

Hazel hazelsphotos [at...] on 11 October 2019 at 17:28Link

I was under the impression that the MCF was not awardable to a driver who finished in the top three. Therefore the MCF for Classics would go to Robert Appleton.

Peter Tattersall on 11 October 2019 at 16:14Link

Anybody have a dead Caterham fuel/oil or temp gauge spare - just need the white plastic cylinder that the electrics sit in - cheers in advance.

Most Consistent Finishers

This year we have four people who have completed ever single races.

The Sigmax MCF is Simon Griffiths with Gareth Cordey just mising out.

The Classic MCF is Trevor Harber with Robert Appleton also finishing all of the races.

Dinner footage needed!

It's getting close to our end of season 'thrills and spills' video - I'm going to be putting this together this year and as you all know, it is a highlight of the awards dinner BUT I can only do it with footage from all of you!

So, if you want to 'star' in the end of season video, please send me your video. Both incidents and funny moments appreciated - crashes, skids, near misses, arm waving, catching wings flying off your car are all welcome! I do need original, high resolution footage wherever possible. For larger clips you can use WeTransfer - just email me if you need more info on how to use it.

Charles on 07 October 2019 at 10:56Link

Just added my motorhome/transporter to the 'for sale' section - please get in touch if interested.

Gareth Cordey on 03 October 2019 at 12:35Link

Just wondering will the results of the survey from ex drivers and competitors who have not driven this year be available at Cadwell Park?

Malcolm Clark on 03 October 2019 at 11:57Link

Cadwell Park

Please find the Cadwell Park briefing note here

The Grids on the BARC timetabes and the briefing notes are now in sync.

JohnB on 03 October 2019 at 10:49Link

Cadwell - Grids 

JohnB - Please can I double-check the Grid 1 and Grid 2 alignment, on the MSV Website they have the class allocation apposite with Grid 1 - 150, 135, 125, Mega & Classics and Grid 2 - SigMax?   

It would be great to clarify so I can confirm to some visitors.. thanks... and thanks for working with BARC to get me onto the Grid this weekend after the entry deadline had passed.. appreciated.

Afternoon all

Looking forward to Cadwell Park as it's definitely our 'home' round given the proximity to CTS HQ.

To that end, I'm on the scrounge for spare tickets for friends and family?  If anyone has any they could pass on I'd be grateful.

Thanks in advance

Cadwell Park - BARC Pit Stop supplimentary race

BARC are running a 45 minute race with Driver Changes at Cadwell on 6th October.
Entry fee is £120.00 per car. Max 2 Drivers in 2 Cars.
His is the Entry Form and Regulations.
All entry by form only. Please note that this is a BARC run event so any questions should be directed to them.

JohnB on 25 September 2019 at 19:12Link


Next year the Sigmax and Sigma classes (150, 135 & 125) will be kept separate as they currently are. The only proposed class mergers are the Mega's into the Sigmax class (with some changes to the Mega spec - this is to be confirmed).

JohnB on 25 September 2019 at 19:09Link


Would it not be better to have the Sigmax and 150 together if that is the intention for next year.

Malcolm Clark on 25 September 2019 at 17:56Link

Cadwell Park

Version 3 of the timetable is now available here

This includes the extra time between races and also an extra practice sessions. At present a final decision on grid split has not been made but it is likely to be the same as Anglesey : Grid 1 - Sigmax, Grid 2 - Classic, Mega, 135 and 150.

JohnB on 18 September 2019 at 21:39Link

Cadwell Park

I have come to an agreement with BARC to place an extra (non CGRC) race in between our races at Cadwell. This gives sufficient time for people to swap cars if they wish to race in two different classes over the weekend. Should anyone be interested please let me know as soon as possible so that I can work on the grid splits to allow this to happen.

The revised timetabe has not yet been published but I will post on here as soon as it is.

JohnB on 17 September 2019 at 09:32Link

As we race in a championship, I believe the qualifying format and length of races needs to be specified at the outset in the Sporting and Technical Regulations; the Club can't just mix things up for a 'random round' during the season to see what drivers might prefer, unless of course that is at a non-championship event.

Mark Carter on 13 September 2019 at 19:54Link

All good comments on the race format and a very helpful clarification from Roger. Personally, I was in the minority too and quite fancy the idea of some form of "random round" where it gets mixed up a bit ! 

There is some really good information in the survey and you can see what the majority want. However, I am sure the Board will see that there are other views and take these onboard when they make decisions for next year.

As an aside, when we get the results of our ex-member and guest surveys, we may see that they want something different to the majority of current members (or not !)

I have to say I was in the (significant!) minority of respondents that would welcome a change to the traditional format of the race weekend. As Kevin says, could be an idea to try it out on a couple of weekends next year and mix things up? Nothing ventured, nothing gained?
