The Wilwood Forged Superlite 4 caliper, part number WIL120-11137, delivers exceptional performance for demanding braking applications on dirt, asphalt ovals, off-road, rally, and road course racing. Designed with advanced features, this caliper incorporates differential bore pistons that effectively compensate for mechanical loading and temperature variances across the pad face, significantly reducing pad taper wear during sustained high-temperature conditions. This design ensures consistent braking performance and longer pad life, making it a reliable choice for high-stress environments. The caliper is equipped with 1.88-inch and 1.75-inch pistons, providing optimal pressure distribution for powerful and controlled braking responses. The forged construction ensures durability and strength, essential for intense racing scenarios and off-road use. It features a lightweight yet robust design, contributing to overall vehicle handling and performance. The caliper's compatibility with a .81-inch disc size makes it suitable for various racing and off-road applications, offering versatility and high-performance capabilities. The inclusion of Thermlock? pistons in the ST models offers an additional heat management advantage, reducing temperatures in the caliper, fluid, and seals by up to 25% compared to standard stainless steel pistons. This heat protection feature helps maintain consistent braking performance during extended periods of hard braking, especially on demanding tracks or rugged terrain. The Wilwood Forged Superlite 4 caliper is engineered for professionals and enthusiasts seeking superior stopping power, durability, and heat management in their braking systems. Its precision manufacturing and innovative features make it a top choice for competitive racing and off-road adventures where reliability and performance are critical.
