Wilwood Front Toyota 4Runner/Tacoma GT Rotor, 13.31 x 1.26 Inches

The 13.31-inch AERO6-DM front conversion for compatible Toyota applications uses this 68-vane GT rotor. A 1.26-inch friction section and 1.180-inch integral-hat offset maintain the geometry of the matching caliper installation. Wilwood’s calipers, rotors, master cylinders, valves, fittings and lines support complete disc brake systems rather than an isolated component choice. Founded in 1977 by Bill Wood and based in Camarillo, California, the company designs and manufactures these systems for motorsport, street performance and specialized applications. Correct pairing of the rotor with its surrounding hardware is essential.
