i dunno, i was racing someone (RL) at 90 and i hit a pothole, steering went really light, car spun round and i clipped the kurb sideways at about 30 i drove off, was lucky actually, because i have adjustable camber on my car it just knocked it out of line, quick suspension stripdown and re-set and all back to normal, althought my wheels are kerbed now due to the pothole
this was on my own private test track...
