The Wilwood Superlite 4R forged caliper (FSL4R) brings race-derived braking to asphalt short track, late model and various road-race applications with a redesigned internal fluid routing that eliminates external crossover tubes. The transfer tube is replaced by two bleed-screw assemblies letting symmetrical piston-bore models be mounted in leading or trailing positions; differential bore units still require left and right orientation.
