Product details
The black left Narrow Superlite 6 uses a nominal 1.10-inch rotor-width channel and differential 1.62/1.12/1.12-inch stainless bores. Its 7416 pads are the narrow format used by the FNSL6R. Bill Wood founded Wilwood Engineering in 1977, and the company is based in Camarillo, California. It designs and manufactures disc brake systems and a component range of calipers, brake rotors, master cylinders, valves, fittings and brake lines serving motorsport, street-performance and specialized installations.

Fitment & Compatibility
Match the left-hand caliper to the rotor centerline and 5.98-inch radial bracket. Verify the complete brake balance for the 4.04-square-inch effective area rather than substituting another six-piston bore combination.
For a replacement or custom installation, send PMB Performance the brake dimensions and existing component identification. Our 20+ years of experience can help narrow down the correct combination.
