Wilwood Rotor-GT48 SPC-37-LH 12.88 x 1.00 - 12 on 8.75in

What you get here is a single Wilwood GT48 curved vane brake rotor, measuring 12.88 inches in diameter and 1.00 inch thick. This rotor is specifically designed for the demanding conditions found in professional motorsports, where managing heat is critical to performance and longevity.

These rotors are constructed from a premium grade, long grain carbon iron. This material choice is key for offering good wear resistance, staying stable under high temperatures, and resisting warping. Wilwood machines every rotor to remove stress points and excess weight from the braking surface. The faces and outer diameter are precisely turned to ensure they are flat and parallel, with minimal run-out, which is important for consistent braking. The unique asymmetrical face slot pattern helps reduce vibrations and balances heat between the inner and outer parts of the rotor, leading to more stable braking performance. Each rotor is also dynamically balanced to ensure smooth operation at any speed.

This rotor is built to offer the highest cooling capacity and longest service life for intense braking situations, like those on short tracks or road courses. If you're pushing your vehicle hard and need braking components that can handle extreme heat without fading, this is a solid option.
