Description
The Wilwood Forged Superlite 4R-ST-L/H brake caliper is engineered for high-performance applications involving sustained hard braking on dirt, asphalt ovals, off-road, rally, and road course racing. Equipped with differential bore pistons, these calipers optimize pad wear performance by compensating for mechanical loading and temperature variations across the pad face, extending pad life and ensuring consistent braking. The inclusion of Thermlock® pistons in the ST models offers advanced heat protection, reducing temperatures within the caliper, fluid, and seals by up to 25%, which enhances durability and reduces the risk of brake fade during demanding driving conditions. The calipers feature a wear-resistant Type III hard anodize finish that withstands harsh environments and aggressive braking cycles, making them a reliable choice for competitive motorsports and off-road use.
Designed with a piston diameter of 1.25 inches and compatible with 1.25-inch disc size, these calipers provide exceptional clamping force and modulation. Their forged aluminum construction offers a lightweight yet robust structure, reducing unsprung weight for improved handling and brake response. Suitable for applications requiring high thermal capacity and durability, the Wilwood Superlite 4R-ST-L/H calipers are versatile, durable, and built to meet the rigorous demands of performance enthusiasts and professional racers alike.
