Wilwood Rotor 1328-130DK799-000UJCXXXXR

This is a Wilwood 1328-130DK799-000UJCXXXXR brake rotor, a 2-piece design measuring 12 inches in diameter. It features a 72-vane internal structure, which is notable for helping to dissipate heat more effectively than a solid rotor. This improved airflow is important for maintaining consistent braking performance, especially during repeated stops or when the brakes are under heavy load.

The rotor is constructed with Wilwood's SPEC-37 iron, a material known for its strength and ability to withstand high temperatures without warping. The hat section is designed for a GT application, meaning it's built to integrate with specific Wilwood brake hat assemblies. Because this is a 2-piece rotor, it allows for thermal expansion and contraction independently of the hat, which can help prevent rotor distortion and cracking over time. This design is often chosen for performance applications where braking demands are higher than stock.
