Wilwood's Forged Superlite FSL4R/ST caliper (left/hand) employs differential bore pistons to improve pad wear characteristics and, for ST variants, Thermlock® pistons that reduce heat transfer into the caliper and fluid by up to 25% compared with standard pistons. A Type III hard anodize finish enhances durability for sustained hard-braking use on dirt, asphalt and road-course environments.
