This ensures a much tighter and precise hold than traditional lug nuts. It also minimizes the chances of scratching your wheels. Made of lightweight composite materials, these open ended lugs fit on both standard studs as well as extended studs. The entire set weighs just under 2 lbs! Highly recommended for both street and track enthusiasts.
Note: Compatible with extended studs if the cap is removed.
