Wilwood Rotor-Subaru Rear 12.19 x .810 - 8 on 7.78in

These Wilwood rotors feature straight vane cooling, a design that helps manage heat effectively, especially during hard braking on dirt tracks or for rear axle use on pavement cars. They're cast from a premium grade, long grain carbon iron, which is chosen for its ability to resist distortion and provide good wear life while maintaining high thermal stability. The faces of these rotors are precision turned to less than .001" variation in flatness and parallelism, ensuring smoother operation and consistent braking performance.

The goal here is to reduce rotating mass while still offering efficient cooling. This combination is particularly beneficial for rear axle service where heat management and responsiveness are key. The material choice and tight machining tolerances mean you're getting a well-built component designed for reliable performance.
