Wilwood Spec-37 Rotor for STM Front Drag Brakes

If it's time to replace the rotors on your STM Front Drag Brake Kit, these Spec-37 rings are a heavy-duty option that are often used with the RS3. These weigh significantly more than the standard lightweight rotor, but can handle more abuse. These rotors have a curved vane design and are side-specific. Rotors are sold individually as needed. Price is for one rotor.
