Wilwood Rotor-GT48 SPC-37-LH 12.19 x 1.25 - 8 on 7.00in

Wilwood's GT 48 rotors are built using their proprietary Spec-37 iron alloy, a material developed to handle extreme temperatures without distorting, warping, cracking, or wearing out prematurely. This alloy comes from technology used in military-spec rotors, so you know it's tough. The rotor measures 12.19 inches in diameter with a 1.25-inch thickness and features an 8 on 7-inch bolt pattern, designed for specific high-performance applications.

These rotors also feature Wilwood's GT Series asymmetrical face slot pattern, which helps clear dust and gas to maintain consistent braking performance. Each rotor is individually dynamically balanced to ensure smooth, vibration-free operation, even at high speeds. This combination of advanced materials and design makes them ideal for demanding uses like short track racing and road courses where cooling capacity and long service life are critical.
