I just took off my 19' wheels for the winter and I have a little vibration in the steering wheel at high speeds with the stock stuff. Im wondering what I should do to correct this. Also it seems that the brakes got a little beat up from the larger wheels but there is a lot of life left on the rotors, can I just have them turned or should I replace them. my car is a 02' A6 3.0 quattro.

Thanks
