Product details
For the left side of the specified 13.50-inch rear conversion, this SRP rotor supplies the corresponding face orientation. The straight-vane iron core does not itself dictate rotation, so the kit’s left/right component assignment is the useful replacement reference. System compatibility is central to choosing a replacement rotor, including its relationship to the caliper, pad and mounting hardware. Wilwood designs and manufactures disc brake systems in Camarillo, California, offering calipers, rotors, master cylinders, valves, fittings and lines across motorsport, street performance and specialized applications. The company was founded in 1977 by Bill Wood.
