Wilwood Caliper-Forged Superlite 4R 1.25/1.25in Pistons 1.25in Disc

This is the Wilwood Forged Superlite 4R brake caliper, a well-known choice for serious performance driving. It's built for demanding applications like asphalt short track, late model racing, and various road-race and rally events. The caliper's design has been updated with internal fluid ports, removing the need for external fluid crossover tubes. This updated design also adds two bleed screw assemblies, allowing for symmetrical piston bore models to be mounted on either side of the vehicle, in either a leading or trailing position. Differential bore models still require specific left and right mounting, but don't need a particular leading or trailing setup.

The Superlite 4R caliper uses 1.25-inch pistons, contributing to its strong performance characteristics. Its forged construction means it's built solid for the stresses of competitive driving. This caliper is a popular option for racers and performance enthusiasts looking for reliable stopping power and a well-built component.
