All A-arms and spindles are made in-house at Full Potential. Rod ends or spherical balls are used at all moving joints. Tires are restricted to any 235/75R15 size and type, but drivers are allowed to cut the tread to their liking. Chad's tires are grooved for improved traction on the track thanks to Precision Race Development of El Cajon, California. Wheels are beadlocked alloys to keep the tires clamped snug during hard cornering and off-square landings.
