Wilwood Rotor-UL32 HP Vented Iron 12.19 x .810 - 8 on 7.00in

This is the Wilwood ULHP-32 straight vane rotor, a 12.19-inch vented iron disc designed for improved cooling and reduced rotating mass. It's a solid choice for applications where hard braking is common, like dirt track racing or for rear axle service on pavement cars. The rotor is cast from a long grain carbon iron, which helps it wear well, handle heat without issues, and resist warping under stress.

What sets these rotors apart is the precision machining. The faces are turned to very tight tolerances, meaning they have less than .001 inches of variation in flatness, parallelism, and run-out. This level of accuracy helps ensure smoother operation and more consistent braking performance. The straight vane design also contributes to efficient heat dissipation, keeping your brakes working effectively when you need them most.
