Billet Superlite 6

The billet SL6 series integrates "Big Brake" style and Wilwood's latest technology into the traditional 3.50" centered lug mount Superlite caliper category. 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 the superior performance of the SL6 comes from the extremely durable, efficient and lightweight body design. Starting at 5.06, pounds it is the product of computer generated solid modeling and FEA 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 Superlite caliper bodies ever built. When compared to open bridge calipers that use tube or stand spacers between the body halves, the closed end bridge design is measurably stronger with less separation or deflection under load. Additional strength and resistance to deflection comes 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 six-piston differential bore configuration provides balanced 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. The SL6/ST models feature Wilwood's exclusive Thermlock® pistons. This multi-part piston design creates a highly efficient thermal barrier to further reduce heat transfer from the pads to the caliper body, seals, and fluid. Cooler temperatures translate to longer service life and less chance for heat induced pedal fade.
