ihm.. are you using always bump/rebound settings the same eg, bump 9 rebound 5 or bump 5 rebound 9 in setup was writen that it mast be similar eg bump 9 rebound 9
When driving a FWD WTCC car, I always set the slow bump settings about the same at the front and back, but back a little higher. I do the opposite for RWD cars - high slow bump at the front, really low at the rear. These allow the car to be more predictable by making the end of the car with higher slow bump stiffer through turns. I generally set the fast bump very low, because I don't want the car to fly up over a bump...
