Has anyone had any experiences with the bolt on wheel adapters? I want to move my wheels out a little bit because they're vette wheels and they sit too far under the fender but I don't trust the cheap wheel spacer plus I don't want to have to install longer lug studs...I just didn't know if these were worth a crap...thanks!!!
