Product details
This Wilwood rear floater conversion supplies black Superlite calipers and 14-inch SRP rotor rings with 72 curved cooling vanes. Separate hats incorporate the internal parking-brake arrangement for the specified Strange Engineering 3.49-inch-offset axle. It is a larger-diameter rear package whose mounting and wheel clearance need to be established from the actual floater measurements. 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
Use DS895 to compare the housing-end mounting holes, register and rotor centerline with the vehicle's axle. The specified floater interface must match even when other axle components have been changed. Assess the chosen wheel's barrel diameter and spoke depth, then check parking-shoe and service-caliper alignment. Plan hydraulic hoses and cable connections separately, with correct system balance established before commissioning.
