Wilwood Billet Superlite 4 Calipers 120-8062-RRD

These Wilwood Billet Superlite 4 calipers feature FEA modeling and stress analysis technology. They also feature a reinforced radial transition between the piston housing body and the solid bridge. That is combined with a full body-length reinforcement rib to give them the highest resistance to deflection and separation under load. Four high-strength steel bridge bolts and a fifth center bridge bolt further add to their superior clamping efficiency, while providing easy access to the brake pads. Superlite 4 calipers are available with stainless steel or Thermolock pistons and equipped with Wilwood's SRS stainless steel bridge plates. The SRS plates eliminate the bridge wear caused by pad gouging and extend the service life of the caliper body. The spring-loaded action of the SRS plates also eliminates pad rattle and dampens the vibration harmonics that contribute to squeal under braking.
