Second guess would be very low rear height which mess the rear geometry.

People don't realize this when they lower the rear. The rear camber curve is not linear.

Yes I am planning to raise the height a bit as it is quite low. My spring rates are quite stiff at 20k front and 18k rear. Should I set the rears height a bit higher than the fronts?

My rear slicks were somehow sliding a lot at the last track day, I thought the tires were done. My rear toe is at 0.07
