The Wilwood Superlite FSLI4 caliper is a competition-grade four-piston caliper developed for short track, late model, modified and open-wheel racing and used across road-race, off-road, rally and sport driving. The FSLI redesign replaces external fluid crossover tubes with internal fluid ports and adds dual bleed-screw assemblies, allowing symmetrical piston-bore models to be mounted left or right in leading or trailing positions.
