i just recently put on some subzero's on my xb, they are 17' and gold. when i first put it on i had some griding problem with the rims and the rear control arms, the problem was soon solved by griding down part of the control arms. But now when i go up to 90+mph i experience a little bit of shaking and also a higher pitch noise from all the wheels. Is there anything i can do? putting a spacer, or a hub ring?
