Rotor 8bt .810 11.75x7.0 UL32

The Rotor 8bt .810 11.75x7.0 UL32 by WILWOOD is a premium performance brake rotor engineered for serious automotive builds and high-demand street or track applications. Designed for vehicles requiring robust stopping power and thermal stability, this rotor serves enthusiasts and mechanics who demand reliability under aggressive driving conditions. Whether upgrading a performance vehicle or building a custom brake system from the ground up, this Wilwood rotor delivers the engineering precision expected from a leader in motorsports brake technology.

The .810-inch rotor thickness provides substantial thermal mass, crucial for dissipating heat during sustained braking events and reducing fade in high-performance scenarios. At 11.75 inches in diameter with a 7.0-inch bolt circle, this rotor balances swept area and mounting compatibility across multiple platform applications. The UL32 designation indicates Wilwood's proprietary casting and friction surface engineering, designed to work seamlessly with performance brake pad compounds while minimizing glazing and maximizing pad life. Weighing 8.25 pounds, the rotor's mass contributes to effective heat absorption without adding excessive unsprung weight to your suspension.

This rotor suits street machines, weekend track cars, and custom hot rods where consistent brake modulation and durability matter. Mechanics and builders appreciate Wilwood's quality control and dimensional accuracy, which simplifies integration into caliper assemblies and reduces fitment issues during installation. Verify your vehicle's brake mounting specifications and caliper compatibility before purchase to ensure proper seating and clearance around wheels and suspension components.
