The Wilwood Forged Superlite 4 caliper, part number WIL120-11138, is engineered for high-performance braking in demanding motorsport and off-road applications. It features differential bore pistons that optimize pad wear and enhance brake response during sustained high-temperature conditions. These pistons assist in compensating for mechanical loading and temperature fluctuations across the pad face, significantly reducing pad taper wear and maintaining consistent braking performance. The caliper's precise engineering ensures reliable operation on dirt and asphalt ovals, off-road trails, rally stages, and road courses.
The Superlite 4 caliper offers an optional Thermlock? piston configuration in the ST models, providing up to 25% heat transfer reduction compared to standard stainless steel pistons. This feature helps keep the caliper, fluid, and seals cooler during intense braking, prolonging component life and enhancing safety. The design incorporates robust forging for strength and durability, making it suitable for sustained hard braking in competitive and off-road environments.
Its compact size and lightweight construction contribute to improved vehicle handling and responsiveness. The caliper's compatibility with 1.88-inch and 1.75-inch pistons further enhances its versatility across a range of high-performance brake systems. With its superior heat management and wear characteristics, the Wilwood Forged Superlite 4 caliper is a trusted choice for racers and off-road enthusiasts seeking reliable, high-performance braking under extreme conditions.
