When i reach 70-80 mph range, the steering wheel shakes really bad, and the car vibrates.
At first I thought it was one of my wheels being off balanced, so i had them all balanced... but it didn't fix the problem.
What else could cause the shaking? I definately know it's coming from a wheel, because it gets worse and higher frequency the higher speed i go.
What else could be wrong? Bent rim? Bubbled on the tire? I did a visual check and it doesn't seem to be any of those.. and when the re-balanced the tires, wouldn't they have noticed that?
Could a warped rotor cause that vibration? I know i have a warped rotor.. but I'm not too sure it would cause a driving problem (other then braking funny, of course).
All this started after I put on the OZ F1's from the 99 oz edition eclipse.
