On my old SRi wheels, my car used to shake a bit on 80MPH and around 100MPH. Was a bit annoying but I could put up with it.
Now i've just put GSi wheels and the shaking has got worse. It's starting at 70MPH and is more vigorous.
The wheels were balanced when fitted, but not tracked. Could this make a difference?
Also, I know I need my front discs replacing because the O/S one is warped. Am I right in thinking this is where most of the shaking is coming from, or is it something else?
