Wilwood Rotor-GT48 SPC-37-RH 12.88 x 1.25 - 12 on 8.75in

What you get here is a single Wilwood GT 48 Curved Vane rotor, measuring 12.88 inches in diameter with a 1.25-inch thickness. This rotor is built using Wilwood's own iron alloy, a material developed to stand up to really high temperatures. It’s designed to resist common issues like distortion, warping, and cracking, even under heavy use. This specific alloy comes from technology used in military-spec rotors, so you know it’s well-built for tough conditions.

The rotor features Wilwood's GT Series asymmetrical face slot pattern, which helps keep the braking surface clear. It’s also individually dynamically balanced, meaning it should run smooth and vibration-free at any speed. These rotors are made for high cooling capacity and a long service life, making them a solid option for demanding situations like short track racing or road course competition where extreme braking is common.
