Brake Rotor 13.06in Dia 1.25in L/H Spec-37 48V

The Brake Rotor 13.06in Dia 1.25in L/H Spec-37 48V by Wilwood is a premium braking component designed for high-performance vehicles and serious modifications. This rotor is ideal for builders and enthusiasts who require precision-engineered parts capable of withstanding extreme thermal loads and repeated hard stops. Whether you're enhancing a street machine, a competition drag car, or a heavy-duty vehicle, this rotor is built for optimal performance.

With a diameter of 13.06 inches and a thickness of 1.25 inches, this rotor offers a substantial swept area and robust mass for efficient brake energy absorption and dissipation. The Spec-37 designation signifies Wilwood's performance-grade material, engineered to resist fade, warping, and thermal cracking during intense braking scenarios. This ensures reliable and controlled braking performance, especially in modified vehicles with increased power or weight.

The left-hand configuration of this rotor is essential for builders planning asymmetrical brake systems, ensuring compatibility with specific vehicle setups. Weighing 12.7 lbs, the rotor is optimized to balance thermal capacity with unsprung mass, which is critical for maintaining suspension geometry and vehicle dynamics. This rotor is a vital component for those seeking to enhance their vehicle's braking capabilities.
