Vehicle Fitment:
• STM Front Drag Brakes
• Replacement vented scalloped rotor

If you need to replace the rotors on your STM Front Drag Brake Kit, this is the lightweight scalloped option. If you previously had the standard rotor, this is a direct replacement as they are interchangeable.

Wilwood Ultralite 32 Vane Scalloped Rotor. When it comes to rotors, racers are constantly searching for the ultimate balance between the lowest weight and the ability to effectively manage heat. Decreased rotating weight in the drive line provides quicker deceleration under braking and quicker acceleration out of the corners. Lower weight also benefits handling with improved spring and shock control over the unsprung suspension mass. Wilwood's ULS-32 scalloped iron rotors provides effective lightweight options for sprints, late models, modified, and other competition applications that race in low to medium temperature ranges.
