Can anyone give me some advice, I have brought and fitted a Bilstein Streetline sports kit to me VR6 as my old suspension was well and truly had it. The new kit lowered the car by 35mm and is now the bumpiest ride in the world, in fact it goes down the road like a see saw! I have been told that it could be due to the fact that the kit came with lowered and uprated springs but was suplied with oe shocks that just are not man enough for the springs. But I have also been told that it could be the bump stops being the wrong height. Anyone got any ideas.
