I have a 92 Corrado VR6 with stock brake calipers. I just purchased a set of 17 by 7 inch MAS Italy Sagitta wheels. I can't bolt them on! I need some sort of wheel spacer. What size should I get and where from??? I know other people have had this problem and just shaved the calipers. I don't want to mess with the calipers, just move the wheel out. If anyone knows anything please help me. Thanks.
