Re. Rear ride height - Could anyone enlighten me as to how different the typical spring preload is from drivers side to LHS? We noticed our car wasn’t very Rake-ish at Silverstone so I’m going to set front ride height and then adjust rear to be 10-15mm higher. 

But on first inspection the LHS rear spring has 25mm  free movement when chassis on axle stands, (rear wheels full droop, uncompressed spring freely moves 25mm up before contacting top spring cup). The drivers spring has about 3-5mm movement. The lower C-Spanner collar shows this difference - I.e collar much lower on thread on LHS compared to RHS.

I’m going to get our car corner weighted and a base setup on flat floor. But probably after Silverstone. So for now I was going to set Front ride height & rake. I know ride height & corner weighting will impact each other, but I was surprised to see such a big difference across the rear of the car? Does it sound unusual? If I set ride ride front left and right the same, then adjust rear pre-load with Adam in car to set rake - could I upset balance of car only doing ride height?
