Wilwood Forged Superlite FSL4R/ST Aluminum Brake Caliper with Thermlock Pistons and 1.88/1.75in Pistons for High-Performance Applications

Description

The Wilwood Forged Superlite FSL4R/ST aluminum brake caliper is engineered for demanding racing and off-road environments, offering exceptional pad wear performance and heat management. Featuring differential bore pistons, this caliper design compensates for mechanical loading and temperature variations across the pad face, significantly reducing taper wear during sustained high-temperature braking. The innovative Thermlock® pistons in the ST models provide up to 25% reduction in heat transfer from the pads to the caliper, fluid, and seals, ensuring consistent brake performance and component longevity under extreme conditions. Constructed with a durable Type III hard anodize finish, these calipers resist wear and corrosion, making them ideal for dirt and asphalt oval racing, off-road events, rally stages, and road course applications. The precise fitment and robust design enable confident high-performance braking, even during prolonged hard braking sequences. Designed for easy installation and compatibility with a variety of brake setups, the Wilwood FSL4R/ST caliper ensures reliable, consistent operation in demanding racing environments. Whether used on dirt tracks, asphalt ovals, or off-road rally stages, these calipers are built to withstand the rigors of high-speed, sustained braking, providing racers and enthusiasts with superior control and durability.
