Wilwood Plain-Rotor Rear Kit for Currie Old Ford Ends — Polished Calipers, 12.19-inch, Blank-Pattern Parking Hats

Plain rotor faces and polished calipers accompany undrilled wheel-mounting sections. Its polished 4-piston calipers and 12.19-inch plain-face rotors are assembled around the requirements of Currie Big Ford Old Style, blank wheel-pattern hats. Wilwood Engineering, founded by Bill Wood in 1977, designs and manufactures disc brake systems in Camarillo, California. The range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications, with each component chosen to suit the complete brake system.

Fitment & Compatibility

This Currie package starts with an old-style Big Ford end and 2.36-inch axle offset, then leaves the wheel bolt circle for final machining. The blank hat section is a manufacturing provision for the wheel pattern, not a description of the disc friction face. Even the drilled-and-slotted SRP versions have undrilled wheel-mounting sections. Establish the intended axle pattern, stud clearance and machining plan before ordering; do not attempt to install an undrilled rotor directly on the axle. DS422 and the axle worksheet identify the mounting dimensions to verify. A Town Car application row does not remove the Currie-end and machining requirements. The finished installation also needs correctly connected parking cables and suitable hydraulic hoses, neither of which is supplied in this brake package.

Print and use the manufacturer wheel template at its specified scale. Check the barrel, spoke shape and offset on the wheels that will actually be used.

Package and installation requirements

• The one-piece iron drum/rotors incorporate the parking-brake drums; the internal shoes provide a mechanical parking brake independently of the four-piston service calipers.
• Parking-brake cables and hydraulic brake lines are separate. Wilwood references universal cable kit 330-9371; installation can require cable or vehicle modifications.
• The wheel-pattern sections are supplied blank. A qualified machine shop must establish the correct wheel bolt circle and stud clearance before installation; this is separate from the plain or SRP rotor friction-surface finish.
