Wilwood Caliper-Forged Superlite 4R 1.25/1.25in Pistons 1.25in Disc
The Superlite 4R caliper series is the benchmark in asphalt short track, late model, modified and open wheel competition. It also enjoys prominence in a variety of road-race, rally and sport driving applications. The new FSL4R model series is the latest innovation to this Superlite family of calipers. It has been redesigned with internal fluid ports that eliminate the external fluid cross-over tubes. The transfer tube has been replaced with two additional bleed screw assemblies which allow symmetrical piston bore models to be mounted either right or left in a leading or trailing position. Differential bore models still require left hand and right hand orientation, but no leading or trailing configuration is necessary.

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately.

Brake Caliper, Billet Superlite 4, Aluminum, Gray Anodized, Wilwood Logo, 4-piston, Each
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.
