I've been playing around with the XRT in patch T and these are the things I've changed in the Easy Race setup to make this car enjoyable and easy to drive
rideheight changed from 0.100 / 0.095 to 0.090 / 0.090
stiffness changed from 48.5 / 55.6 to 60.0 / 70.0
Toe in front from -0.1 to 0.0
Toe in rear from +0.1 to 0.0
clutch pack LSD from 20% / 40% to 25% / 45%
camber front from -0.2 / -0.2 to -1.6 / -1.6
camber rear from -1.0 / -1.0 to -1.8 / -1.8
This works really well for me. Stille a little understeery in the hairpins but overall its pretty good.
