Red six-piston calipers pair with drilled/slotted 12.88-inch rotors in this Wilwood front ProSpindle conversion. New hubs, bearings and BP-10 pads are supplied with the mounting components. Its one-piece rotor package and bracket geometry must match the installed suspension upright. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines. Its product range serves motorsport, street-performance, and specialized applications, with individual components selected to match the requirements of the complete brake system.

Fitment & Compatibility

Inspect the actual ProSpindle against DS869, checking the hub and bearing arrangement before ordering. Verify the wheel bolt circle and the effect of the published outward mounting offset on the chassis. The brake kit does not establish fitment for another spindle solely because it fits the same vehicle. Brake hoses are separate choices and must remain clear at steering lock and full suspension travel. Confirm the conditional 17-inch wheel section, then set caliper alignment and perform the required brake tests.
