Low Vibrations........

[get1]

Ever since i have lowered my VX i have had a vibration which only occurs under load / acceleration. It's been lowered at pedders roughly 2 1/2 inches at the rear and 2 inchs at the front.

I have taken the car back to pedders and was told it must be something different such as diff etc as they have lowered hundreds of commodores with out getting this problem.
Holden says its because i have lowered it and now the tail shaft angles are out. Is this true?????? or any idears to what it could be as its making my driving experience about as much fun as a fart in a wet suit.:bang:
