Rotor Spec-37 8bt 11.75 x 1.00 16 Vane RH

The Wilwood Rotor Spec-37 8bt 11.75 x 1.00 16 Vane RH is a premium brake rotor engineered for high-performance automotive builds where thermal stability and stopping power are non-negotiable. Designed for serious track enthusiasts, drag racers, and custom hot rod builders, this right-hand rotor delivers the precision engineering demanded by vehicles running heavy-duty braking systems. Whether you're upgrading a street machine or building a dedicated competition platform, the Spec-37 series represents Wilwood's commitment to fade-resistant performance under extreme conditions.

At 11.75 inches in diameter with a 1.00-inch thickness, this rotor provides substantial thermal mass to dissipate brake heat quickly and maintain consistent friction characteristics across repeated high-load stops. The 16-vane internal cooling design accelerates air circulation through the rotor core, a critical feature for preventing brake fade during sustained hard braking or prolonged track sessions. Wilwood's proprietary rotor construction combines high-carbon iron with precision machining to create a component that resists warping and maintains superior surface finish consistency—essential when paired with OEM or aftermarket calipers that demand tight tolerances and predictable modulation.

This rotor is ideal for independent suspensions and performance brake packages where right-hand rotor geometry is specified; verify your vehicle's caliper mount configuration before purchase to ensure correct fitment. The Spec-37 series is particularly suited for applications that require high-performance braking capabilities, making it a top choice for those who push their vehicles to the limits on the track.
