Product details
The black SRP assembly equips the specified C10 modular spindle with drilled-and-slotted Spec-37 rings and AERO6 calipers. BP-10 pads accompany this drilled version, differing from the GT kit's BP-20 specification. Hats and brake hardware are included. Wilwood Engineering, established by Bill Wood in 1977 and based today in Camarillo, California, manufactures and designs disc brake systems and their components. The product range covers brake rotors, calipers, valves, master cylinders, brake lines and fittings for motorsport, specialized and street-performance applications. Suitability depends on matching each component to the entire brake system.
