Drilled Rotor 8BT .810in x 11.75in

The Wilwood Drilled Rotor 8BT .810in x 11.75in (part number 160-5863) is a high-performance brake rotor engineered for vehicles demanding lightweight, thermally efficient stopping power. This drilled rotor features an 11.75-inch outer diameter with 0.813-inch thickness and an 8-bolt x 7.000-inch bolt pattern, designed to maximize heat dissipation through its ventilated, drilled construction while maintaining structural rigidity under sustained braking loads.

The ultralite 32 design delivers a 7.65-pound rotor that significantly reduces unsprung weight compared to solid alternatives, improving handling response and reducing brake fade during extended use. The drilled pattern serves dual purposes: it provides escape routes for gas and water vapor that accumulate between the rotor and pad surface, maintaining consistent friction and extending pad life, while the weight reduction contributes directly to improved vehicle dynamics. Iron construction ensures proven durability and compatibility with a wide range of brake pad compounds, without the brittleness risk associated with carbon-ceramic designs in street or track environments.

This rotor is specified for applications where thermal management and weight savings are critical—high-performance street cars, road racing, and motorsport platforms where every pound matters. The 8-bolt configuration and 7.000-inch diameter ensure fitment verification against your specific vehicle's hub and caliper setup. Natural iron finish resists corrosion under normal service, though regular cleaning maintains optimal appearance and function.

Wilwood rotors are purpose-built for systems where brake performance directly impacts safety and vehicle control. Verify bolt pattern, caliper clearance, and brake pad compatibility with your specific platform before purchase to ensure proper installation and braking performance.
