They have been mounted and balanced only one time (using tape weights) and driven less than 30 miles. This type of wheel originally came on 1993-1997 SS Camaros. They are slightly different than the wheels used on 1998-1999 SS Camaros. This is why I'm selling them -- they don't match the wheels I already have and SLP won't take them back because they've been mounted and can not be sold as "new."
