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

This is a Wilwood 12.19-inch diameter, 0.810-inch thick vented iron brake rotor, featuring a drilled pattern and an 8 on 7.00-inch bolt circle. It's designed for competition applications where managing heat and reducing weight are critical for performance. Racers often look for ways to decrease rotating mass because it can lead to quicker acceleration out of corners and more responsive braking. Lowering unsprung weight also helps suspension components like springs and shocks work more effectively, improving overall handling.

The ULD-32 iron rotor from Wilwood offers a lightweight option specifically for racing series like sprints, late models, and modifieds. Its drilled design helps dissipate heat, making it suitable for racing environments that experience low to medium temperature ranges. While it's built for performance, it's important to note that drilled rotors can sometimes be more prone to cracking under extreme heat cycles compared to solid or slotted rotors, so they are best suited for their intended competition use.
