Use these setup wheels to get your alignment set accurately and quickly. Made from Billet aluminum, the setup wheels are sold in sets of 4. This is an Integy INTT7012SM 1/10th Scale Silver Aluminum Touring Car Setup Wheel Set. These bolt onto your car instead of your normal tires and wheels to provide you with a flat surface on the outside edge to make setting camber and toe-in easier and more accurate. If you try to adjust these settings with normal tires on, the shapes of the tires make it hard to get accurate measurements of camber and toe. The set includes four wheels abd metric nuts.'
