Here are 2 graphs of the Radical GT3 where i pushed throttle 3 times for short period on a straight, 1st gear. After each short push I waited until car slowed down to 75km/h again. The damper were set in "soft" state to all 1, in "stiff" state the slow damper to max = 50. It´s obvious for stiff condition the suspension forces on rear go crazy when just rolling, not reaching balanced queal condition (and even in dynamic load change you can see plateaus and other harsh locks). This is a clear bug in the suspension model. To reproduce just set all damper to max. and go around and observe suspension forces
