The Buddy Club Chrome Racing Lug Nuts are extended and open ended. They're 50mm in length and made of Forged Steel. These lug nuts are heavy duty and duarable for both street and track purposes. Made to work with extended studs. The chrome look really sets off many different styles of wheels that have polsihed lips or chrome/polished center caps. Even on wheels without any chrome, the chrome lugs become the focal point of the wheel.
