Wilwood HPS GT-Slotted Iron Rotor, 12.19 x 1.10-inch, Plain Finish

Straight cooling vanes allow this slotted HPS ring to serve either side of a compatible brake system. Its plain finish leaves the iron appearance visible, while the 12.19 x 1.10-inch envelope must match the caliper and separate hat. Bill Wood established Wilwood Engineering in 1977; the company is based in Camarillo, California and designs and manufactures disc brake systems. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form its range for motorsport, street-performance and specialized applications. Compatibility depends on selecting those parts for the requirements of the complete brake system.

Fitment & Compatibility

Compare the existing hat interface with the 8 x 7.00-inch rotor pattern, then check the 6.45-inch centering register. Proper axial placement and full pad contact are required around the 12.19-inch ring. A matching wheel-bolt pattern is not a substitute for this rotor-to-hat check.
