i've got a lowered sierra sapphire which has a very bad vibration problem at any speed over 50mph. i have already replaced the wheels as i thought it was down to the old 1's being buckled. this didn't help at all. can anyone shine some light on my problem PLEASE! could it be the prop or has it got something to do with being lowered?
