Wilwood 160-8136 UL32 Vented Scalloped Iron Disc Brake Rotor

The Wilwood UL32 Series Scalloped Iron Rotor is engineered for competitive racing applications including sprints, late models, modifieds, and other vehicles operating in low to medium temperature ranges. This lightweight performance rotor delivers the critical balance between reduced rotating mass and effective heat management that racers demand.

Key Features:

• Fully machined scallop configuration removes up to 3 pounds or nearly 33% of rotor mass
• Vented straight vane design provides superior cooling capacity compared to solid machined steel plate rotors
• Improved structural durability over drilled rotor designs reduces risk of cracking
• Reduced rotating weight enables quicker deceleration under braking and faster acceleration out of corners
• Lower unsprung mass improves suspension performance and spring/shock control
• Cast iron construction optimized for racing in low to medium temperature environments

The scalloped design represents the highest degree of weight reduction achievable on a vented straight vane iron rotor while maintaining the structural integrity and cooling performance required for competitive motorsports applications.
