Wilwood 160-17781 11.75" Super Alloy Slotted Brake Rotor

The Wilwood 160-17781 is an 11.75-inch diameter slotted face disc brake rotor constructed from Wilwood's proprietary Super Alloy material. This advanced rotor design offers dual mounting options for maximum versatility: choose between Wilwood's innovative Lug-Drive dynamic floating mount system or the conventional 8-bolt on 7.00-inch bolt pattern configuration.

Key Features:

• 11.75-inch diameter slotted face design for improved cooling and pad bite
• Dual mounting options: Lug-Drive floating mount or 8-bolt pattern (7.00" bolt circle)
• Proprietary Super Alloy construction for extreme weight reduction
• Superior resistance to degradation, shrinkage, and warping compared to lightweight iron and steel rotors
• Excellent thermal distortion resistance through specialized manufacturing processes
• Optimized friction and wear characteristics for consistent braking performance

Wilwood's Super Alloy material delivers the lowest possible rotating and unsprung weight without sacrificing durability or performance. These rotors are engineered for applications where sustained temperatures remain in the low to moderate range with only intermittent high heat spikes, making them ideal for street performance, autocross, and light track use. The slotted face design enhances pad cleaning and gas evacuation while the Super Alloy construction maintains dimensional stability throughout the rotor's service life.
