Product details

The red SRP assembly includes six-piston front calipers, 12.88-inch rotor rings and the matching aluminum hat/hub components. Its wheel interface is the current modified 5 x 5-inch hub specification, with separate brake lines required for the vehicle. 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.

Fitment & Compatibility

Check the specific Wilwood ProSpindle layout before ordering. DS1115 gives distinct mounting instructions for standard and drop configurations. Verify the 5 x 5 wheel pattern, +0.68-inch hub shift and full internal wheel envelope; neither the spindle nor hydraulic hoses are part of this kit.

With more than 20 years of parts experience, PMB Performance can help review the specified brake arrangement. Include the vehicle year and details of any hub, spindle or suspension changes.

Check the Installation instructions for the full assembly and wheel-clearance requirements.
