Description

Engineered to deliver the pad wear performance advantages of differential bore pistons, Wilwood forged Superlite 4 radial mount calipers also provide ultimate heat protection in the ST models. The differential piston bores compensate for leading-edge mechanical loading and temperature variances across the pad face. The Thermlock pistons in the ST models block heat transfer in the pads and reduce temperatures in the caliper, fluid, and seals by up to 25 percent over standard stainless steel pistons.

Additional information:

* Billet aluminum caliper material
* Black anodized or nickel plated finish
* Four-piston calipers
* Various rotor thickness and piston diameters available
* Calipers include Wilwood logo
