Product Details
The Thermlock® pistons in these Wilwood Superlite 4R-ST-R/H calipers are a notable design choice, specifically engineered to block heat transfer from the brake pads. This advanced feature helps reduce temperatures within the caliper, fluid, and seals by as much as 25% compared to standard stainless steel pistons, making them a solid option for sustained hard braking.
These calipers also utilize differential bore pistons, with bores measuring 1.88 inches and 1.62 inches. This design helps compensate for leading-edge mechanical loading and temperature differences across the brake pad surface. The result is reduced pad taper wear, especially in high-temperature situations. The wear-resistant Type III hard anodize finish further contributes to their durability, making them a popular choice for demanding applications like dirt and asphalt ovals, as well as various off-road, rally, and road course events.
