Spent 2 days at NHIS with the Rs and RSR. The rs is totally transformed from stock, absolutely a different car!!! Steering is lighter ( due to complete lack of rubber?) but the car is very well balanced and composed. Obviously the Hoosiers are also alot to do wth the transformatiuon.
Lapping with my partner ( pretty close abilities) in the race car, the Rs was not at a great dissadvantage in many places on the track. The RSR was obviously faster, but the Rs was an absoulte blast!
Well balanced, intuitive
In fact the JRZ seem better than the motons on the race car, in the video / data you can see residual motion and oscilation on transition to / off the oval is beter )less) on the RS ( shocks have been set up on a dyno to be as close as possible.)
When I get a few minutes I will post a video of both cars lapping
Highly reccomend the full suspension mods! only downside is the cayman ($)stuffed under the car
can't wait for the composite body phase

What spring setup did you go with, rate wise?? I have much of what you did, except the uprights and subframe reworking on my GT2... I also have Motons but think I need stiffer springs now a days from the 600-800, too soft for me :/ So here is my question, 800-1000, will it make my back end that much more snappy, some seem to think so??
Also funny you mention your steering feels lighter, so does mine.. I was expecting a tighter more direct feel, but it isn't which is very odd, anyone have the answer for that?

I think that lowering the roll center of the car has alot to due with making the vehicle more neutral, and preventing snap oversteer. My builder insisted on this, and he has worked for major race teams in the past, so in an unusual move, I listend to him.
See above prior for spring rates installed, rates are totally acceptable, and could no doubt be heavier on a smoother track like WGI / LCMT, etc.
I will dial in additinal HS rebound damping, to slow the wheels return to earth on stutter-braking bumps a litttle.
Suspension has alot of adjustment to learn.
