Wilwood Rotor-GT48 SPC-37-RH 13.06 x 1.38 - 8 on 7.00in

If you're pushing your vehicle hard on short tracks or road courses, you know how critical brake performance is. These Wilwood GT 48 rotors are built to handle the intense heat generated during competition braking, helping to prevent the common issues like warping and distortion that can ruin a track day.

Wilwood developed a special iron alloy, Spec-37, for these rotors. It's a well-built material that stands up to extreme temperatures, drawing on technology used in military-spec rotors. The GT Series asymmetrical face slot pattern helps clear heat and debris, while individual dynamic balancing ensures a smooth, vibration-free feel even at high speeds. This combination means you get a rotor that offers excellent cooling and a long service life when you need it most.
