snippet: Wheel spacer hardware should be replaced at regular intervals as a wear item. As a rule of thumb, many who track their vehicle replace their wheel hardware every 7 hours of track use. For cars that see strictly street duty, hardware should be replaced in two-year intervals. All wheel fasteners are hardened and tempered to strength class 10.9 or 10 according to DIN/ISO standard 898. Our replacement hardware set is identical to the pieces that ship with your existing wheel spacer kit. For custom quantities, please contact us.
