The Wilwood Superlite caliper series is the benchmark in short track, late model, modified and open wheel competition. It also enjoys prominence in a variety of road-race, off-road, rally and sport driving applications. The new FSLI 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, along with any potential problems that could arise from a damaged tube. The transfer tube has been replaced with two additional bleed screw assemblies which allows this group of symmetrical piston bore models to be mounted either right or left in a leading or trailing position. Select the size caliper that matches your rotor thickness (0.81″ or 1.25″) and piston size (1.38″ or 1.75″) that works best with your master cylinder and brake pedal setup.
These are for 12″-13″ diameter brake rotors only. These all have the 3.5″ spread bolt pattern.
