Does anyone know what is wrong with my car/wheels?.. i have recently bought some AMG monoblock II replicas off a friend for £100 (no buckles, no curb marks and with 4 brand new tyres with 0 miles BARGAIN!?) ive recently had them put on from my local garage getting the wheel alignment done at the same time. the wheels are facing dead straight, and the mechanic has showed me the laser positioning confirming they are spot on. However.... now i cant go over 60mph without the steering wheel shaking... faster i go, the more it shakes. bring it down to 50mph and the vibrating stops... What could it be?? it is doing my head in! Any help is appreciated Thanks in advance!
