Product details
The slotted GT face gives this right-hand 12.19-inch rotor its friction-surface treatment. Wilwood balances the 48-vane Spec-37 ring; this version is supplied without factory burnishing and needs the appropriate pad-and-rotor bedding procedure. Wilwood Engineering is based in Camarillo, California and was founded by Bill Wood in 1977. It designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. The range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines, all of which require selection around the full brake system rather than an isolated dimension.

Fitment & Compatibility
Installation requires a hat or hub designed for the 6.38-inch rotor register and 8 x 7.00-inch attachment. Verify wheel clearance around the complete caliper, along with the rotor's 1.25-inch width. The ring alone does not define a direct-fit vehicle or axle application. Select pads and operating duty to suit the rotor material and the intended brake system.
