The Wilwood Forged Superlite FSL4R/ST aluminum brake caliper offers advanced performance features designed for high-stress braking applications on dirt, asphalt ovals, off-road, rally, and road courses. Engineered with differential bore pistons, these calipers improve pad wear performance by compensating for mechanical loading and temperature variations across the pad face, effectively reducing taper wear during sustained high-temperature braking. The FSL4R/ST models incorporate Thermlock? pistons that significantly lower heat transfer from the pads, leading to a reduction of up to 25% in temperatures within the caliper, fluid, and seals, which enhances durability and reduces risk of overheating during demanding driving conditions. The calipers feature a wear-resistant Type III hard anodize finish, ensuring longevity and resistance to harsh environments, making them ideal for aggressive braking scenarios on both dirt and asphalt surfaces. Designed with precision and durability in mind, these calipers are suitable for a broad range of motorsport and off-road applications, providing reliable performance under sustained hard braking.
