Wilwood FSLI4 Caliper: Engineered for Extreme Braking Demands

The Wilwood FSLI4 caliper is designed to meet the rigorous demands of high-performance driving and racing. Its key feature, the differential bore piston design, effectively combats pad taper wear by compensating for varying loads and temperatures across the brake pad surface, ensuring consistent and reliable stopping power.

FSLI4/ST Calipers: Enhanced Heat Management

For applications requiring maximum heat resistance, the FSLI4/ST models incorporate Thermlok pistons. These specialized pistons significantly reduce heat transfer from the brake pads to the caliper body, brake fluid, and seals, potentially lowering operating temperatures by up to 25% over standard stainless steel pistons. This makes them indispensable for prolonged high-stress braking scenarios.

• Differential Piston Sizes: Features 1.88-inch and 1.75-inch pistons to optimize pad engagement and minimize taper wear.
• Disc Compatibility: Engineered for use with .81-inch discs, providing a robust braking solution.
• Ideal For: The preferred choice for sustained hard braking on various racing surfaces, including dirt and asphalt ovals, off-road, rally, and road course events.
• Internal Fluid Ports: Eliminates external cross-over tubes, enhancing durability and simplifying the caliper's profile.
• Dual Bleeders: Includes two bleed screw assemblies for efficient and thorough brake fluid service.
