Description

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.
