Wilwood Billet Superlite 6 Calipers

These billet SL6 series calipers integrate "Big Brake" style and Wilwood's latest technology. Each caliper is precision CNC-machined from high-strength billet into three specialized configurations that cover a broad range of competition and sports driving applications. The key to their superior performance is their extremely durable and efficient body design. It is the product of FEA computer solid modeling and stress analysis technology. Full-length stiffening ribs and a reinforced radial transition from the piston bore housings to the closed-end bridges have produced the strongest caliper bodies ever built, according to Wilwood. When compared to open-bridge calipers that use tube or stand spacers between the body halves, the SL6 calipers' closed-end bridge design is measurably stronger, with less separation or deflection under load. Additional strength and deflection resistance come from the four high-strength steel end bridge bolts. A fifth center bridge bolt provides even more overall strength and easy access to the pads, without the need to remove the caliper from the mount. A unique 6-piston differential bore configuration provides balanced pad loading for even pad wear in sustained high-heat environments. The standard SL6 calipers feature one-piece stainless steel pistons. Stainless is used for its slow heat transfer properties and high resistance to corrosion. Show Less
