Product Description

FSLI4 and FSLI4/ST calipers provide the pad wear performance advantages of differential bore pistons with the option for ultimate heat protection using Thermlock pistons in the ST models. Differential piston bores compensate for leading-edge mechanical loading and temperature variances across the pad face to reduce pad taper wear in sustained high temperature applications. Thermlock pistons in the ST models block heat transfer from the pads and reduce temperatures in the caliper, fluid, and seals by up to 25% over standard stainless steel pistons. These are the go-to calipers for all types sustained hard braking on dirt and asphalt ovals and a wide range of off-road, rally and road course applications.

These Wilwood Forged Superlite Internal (FSLI) brake calipers feature internal fluid ports that eliminate the external fluid crossover tubes, along with any potential problems that could arise from a damaged tube. The transfer tube has been replaced with two additional bleed screw assemblies, which allow this group of symmetrical piston bore models to be mounted either on the right or left in a leading or trailing position. They are also stress-flow forged from premium-grade aluminum alloy billets. Stress-flow forging realigns the metal's internal grain structure to flow within the contour of the caliper body. This process eliminates the stresses and interruptions to the internal grain structure that occur when machining a straight block billet. The FSLI body design is a highly efficient product of computer-generated solid modeling and stress analysis technology.
