Rotor GT 48 SPC 37 RH Burnished 11.75in

The Rotor GT 48 SPC 37 RH Burnished 11.75in from Wilwood represents a premium brake rotor engineered for serious automotive performance applications. This right-hand rotor is built for drivers and shops who demand maximum stopping power, heat dissipation, and durability under extreme braking conditions. Whether you're upgrading a street-driven performance car, preparing a track vehicle, or rebuilding a custom suspension system, this rotor delivers the thermal capacity and structural integrity required for reliable, fade-resistant braking.

Wilwood's Rotor GT series features advanced vented geometry and burnished surface finishing that work together to accelerate pad bedding and reduce initial glazing. The 11.75-inch diameter and SPC (performance-grade) construction provide excellent thermal mass for absorbing and dissipating braking heat, critical for sustained high-performance driving where brake fade is a real concern. The right-hand orientation ensures proper fitment on compatible brake kits, and the burnished finish—a precision treatment applied during manufacturing—promotes more consistent friction characteristics from the first brake application. The rotor's 37-position cooling vane design balances airflow efficiency with structural rigidity.

This rotor is ideal for drag racing, road course competition, autocross events, and high-performance street builds where OEM brakes are no longer sufficient. Mechanics and fabricators favor Wilwood rotors for their precision machining, consistency across production batches, and compatibility with Wilwood's matched brake systems and calipers. Installation requires mounting to a Wilwood brake hub or compatible adapter; verify your caliper offset and pad material before selection to ensure optimal bite and minimal runout. Weighing 10.35 lbs, the rotor integrates seamlessly into custom and OEM-based brake upgrades across domestic and import platforms.
