Product details
Wilwood combines 14-inch GT slotted rotors with black Superlite 4R calipers in this rear parking-brake package for the specified Strange floater. The Spec-37 rings use 72 curved vanes and attach to separate hats. Internal shoes provide parking actuation, while the 3.49-inch axle offset determines how the service calipers align with the rotors. 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
Match the floater flange, bearing/register dimensions and offset to DS895 and the axle worksheet. An 18-inch wheel screening size cannot confirm spoke clearance by itself; inspect the full radial and axial outline. Check the hat mounting interface on the existing floater assembly before installation. Hydraulic hoses and mechanical parking-brake connections are separate and need suitable clearance throughout suspension movement.
