Progress Camber Kits are designed to provide optimum tire wear after installing Sport Springs. For the Pivot Mount Type, new billet steel pivot mounts relocate the upper control arms further outboard. This moves the top of the tire out for additional positive camber. Polyurethane bushings improve cornering and drag launch. Includes Teflon grease, thread locker, and all necessary hardware. For the Ball Joint Type, new adjustable upper ball joints feature offset mounting studs. By rotating the new ball joints, positive or negative adjustments are possible. caster changes can also be made. A favorite for autocrossers, because street and racing settings are easy to make. For the Offset Bushing Type, new polyurethane bushings and offset steel inserts replace the rubber upper control arm bushings. Rotating the steel inserts moves the control arms for camber adjustment. Control arms are not included for all types.
