Has anyone used wheel spacers? I bought some 1" wheel spacers as my rear tires rubbed a tad when I turned and hit a bump. The studs on the existing hub are slightly to long and my rim hits the old studs when I mount my tire. I used a flat washer and a locking washer on the wheel spacer stud then put my rim on as then it would clear the old studs. Does anyone see a problem with this??
