Car's fully together with the new 245 A052's and wheels. Still does the same thing. I tried all different settings throughout the day at this test and tune with about 15 runs.
It appears to only be on right hand corners. Lefts are much better, although there's only one slight one here. At last week's event there was a long left sweeper and the car was planted and on point there.
From what I can feel, the inside passenger side rear wheel feels like it's off the ground. The car bounces and bobs, then you go to get on power and it shoots up to redline. In some videos you can hear it skim the surface during this and then hook up. Stock 2017-2020 rear swaybar (15mm). Front is a Perrin 19mm set on stiff (72% increase over stock). I mostly adjusted on the higher end of the settings working my way up in 2 click increments from the recommended 8F/10R from stiff. I tried at near full stiff and it was still doing it. I don't believe it's a setting/rebound issue. It also does it near full soft.
The VERY odd thing is the rear drivers side needed to be set a full 1.5" higher than the rear passenger side to get the same static ride height (~26" from the ground, even. About a 3 finger gap.) I'm current theory is the spring shouldn't be compressed that much and something is going on there. RCE recommend between 5-6" from the bottom of the spring to the LCA bolt. The passengers side is at 5.5" and drivers at 7".
