Product details
Wilwood's 12.88-inch rear package brings black Superlite 4R calipers and GT slotted rotors to the specified Strange Engineering floater axle. Separate hats carry the 48-curved-vane iron rings, with an internal shoe assembly handling the parking brake. The complete arrangement is selected by the 3.49-inch axle offset and the floater mounting geometry. 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 for motorsport, street-performance, and specialized applications.

Fitment & Compatibility
Check the housing-end flange, register and measured offset against DS894 before ordering. The rotor hats attach to the floater arrangement and should not be mistaken for a conventional wheel-pattern conversion. Confirm 17-inch wheel screening clearance with the actual template, including the spokes. Parking cables and hydraulic lines are separate, and the system's hydraulic balance must suit the completed front and rear brakes.
