I just put on solid SPL bushings up front (compression, inner lower arm, and shock lower arm) and SPL V3 upper arms.

I just put my car up on the rack, and I am thinking that the rack may be inaccurate. It's a Hunter at a Nissan and has seen some abuse over the years. We calibrated it twice to double check before we started and even then, the numbers up front were quite inconsistent.

Anyway, I set up my upper control arms with plans to have -2.5 camber and 9 degrees of caster. So I have the 2 degree shim in the arms for camber (should be -1 degree from stock) and I threaded the front bolt of the arms out just less that 0.3" which should bring me from 8 degrees to 9 degrees caster.

After aligning, The caster was at 10 degrees on both sides and the camber was at -2.5 and -2.2. I can't imagine that there is anything bent on my car as it is accident free.

For anybody with the SPL arms and solid bushings, do you have any issues like this?

And since I haven't seen it answered and other people may wonder, how much caster is too much? What will be the downsides here if it really is 10 degrees? This isn't my daily driver and I will be using it regularly for autox and HPDE's.

 

Ride height can make the camber vary.... If you have coils
