Drilled Rotor 8Bt .810in x12.19in

The Wilwood Drilled Rotor 8Bt .810in x 12.19in (part number 160-5865) is a high-performance brake rotor engineered for vehicles requiring superior cooling and consistent braking force under demanding conditions. The drilled rotor design facilitates rapid heat dissipation and helps shed water and brake dust, making it ideal for extended braking cycles, track use, and high-performance street applications where fade resistance is critical.

Specifications are optimized for compatibility with 8-bolt patterns at 7.000 inches, with a finished thickness of 0.813 inches and an outside diameter of 12.19 inches. The rotor is constructed from cast iron and weighs 8.45 lbs per unit, providing the thermal mass necessary to handle repeated hard stops without temperature-related performance loss. The drilled design reduces unsprung weight compared to solid rotors while maintaining structural integrity, a consideration particularly important in vehicles where suspension responsiveness and braking consistency go hand in hand.

This rotor suits builders and operators upgrading brake systems on performance vehicles, off-road applications, and vehicles subjected to sustained or aggressive braking. The 12.19-inch rotor is commonly specified in medium-duty brake packages across various platforms. Wilwood's manufacturing tolerances and iron composition are known for consistent friction characteristics across temperature ranges, a requirement for systems where pedal feel and stopping distance cannot vary between the first stop and the hundredth.

Purchase the Wilwood Drilled Rotor 160-5865 as a single rotor or as part of a complete brake system upgrade. Always verify bolt pattern compatibility and rotor diameter against your vehicle's caliper and hub specifications before installation.
