Billet Narrow Superlite 4
The Superlite caliper series has set the standard for many years in short track, late model, modified and open wheel competition. It has also enjoyed prominence in a variety of road-race, off-road, rally and sport driving applications. Starting at 4.40 pounds, the Forged Billet Superlite (FSL) is the newest innovation to this series from Wilwood. New and adaptive technologies have been applied providing substantial improvements in strength, fluid volume displacement, and overall performance.  

The FSL body design is a highly efficient product of computer generated solid modeling and stress analysis technology. Each caliper features closed end bridges with a radial transition to the piston body housings. The elimination of machined steps and sharp shoulders in this critical area provides a measurable increase in overall body strength and resistance to deflection under load. Center bridge bolts replace cotter pins to provide additional support and allow quick access with positive brake pad retention. Clamping force, structural deflection, and volume displacement tests have proven the superior strength and efficiency of the FSL. On-track testing has proven driver satisfaction. The bottom line is better stopping power with less pedal travel.   Continue >>
