For this install, large 24-inch wheels were going to be installed, but to show you how cool the kit is, you can actually use your stock 17-inch wheels with the McGaughy's kit by grinding off the small remnants of the lower ball joint stud protruding from the bottom of the spindle. If 17s are not in your future, this stepcan be ignored.
