Wilwood Superlite FSLI4 Differential Bore Caliper High-temperature stopping power engineered for sustained, hard braking in racing and aggressive street use. The Wilwood Superlite FSLI4 caliper delivers precision pad wear control and thermal management for dirt and asphalt ovals, off-road, rally and road course applications. Key Features Differential bore pistons — Compensate for leading-edge mechanical loading and temperature gradients across the pad face to minimize pad taper and extend pad life. Thermlock® piston option (FSLI4/ST) — Reduces heat transfer from pads to caliper, fluid, and seals by up to 25% vs. standard stainless pistons for improved reliability in high-temperature conditions. Lightweight Superlite design — Optimized for performance without compromising stiffness or pedal feel. Versatile application — Ideal for sustained heavy braking on short-track ovals, off-road competition, rally stages, and demanding road-course use. Benefits Improved pad life and more consistent wear patterns Lower caliper and fluid temperatures with Thermlock® option Greater resistance to fade and reduced maintenance intervals Choose Wilwood Superlite FSLI4 for engineered thermal control and optimized pad performance when every stop counts.
