Well, I have replaced new rotors and brake pads on the front. The rotors were pretty worn out. The vibration is less, and less violent. It also seems to smooth out when I get pass 75-80 mph. The vibration still occurs about 55-60 mph. I don;t think it was aligned properly. The car seems to drift to the right. Can this also cause vibration?

Also, the driver's rear is about an inch lower than the passenger's. Can this affect the vibration? I will plan to the rear spring later. Probably will look at the rear rotors at that time also.

Thanks,

John
