Rotor GT36 SPC37 RH 11.75 x .810 8 on 7in

The Wilwood Rotor GT36 SPC37 Right-Hand brake rotor delivers purpose-built stopping power for high-performance and heavy-duty braking applications. Engineered with a directional, slotted design and iron construction, this 11.75-inch outer diameter rotor is optimized for vehicles running the 8 on 7-inch bolt pattern, making it an ideal upgrade for operators and enthusiasts who demand repeatable, fade-resistant braking performance in demanding conditions.

The rotor's 0.810-inch thickness and slotted vane geometry work together to manage heat dissipation and reduce brake pad glazing—critical factors when running hard stops repeatedly during patrol duty, training exercises, or high-speed operations. The directional design channels debris away from the braking surface, extending pad life and maintaining consistent friction coefficients across extended use cycles. Cast iron construction provides the thermal mass and durability required for sustained braking loads without warping or checking.

This right-hand rotor is engineered for vehicles equipped with the 8 on 7-inch bolt pattern and compatible brake hardware. The natural iron finish requires standard maintenance practices to prevent corrosion in wet or salt-air environments, consistent with typical ferrous brake rotor care. Weighing 9.75 pounds, the rotor fits standard mounting specifications for its class and integrates seamlessly into existing brake assemblies without modification.

Wilwood brake rotors are selected by operators and technicians who prioritize thermal stability and predictable braking feel under load. The GT36 platform is proven in both street and competition environments where fade-free performance is non-negotiable. Whether upgrading a duty vehicle, competition rig, or off-road platform, this rotor delivers the heat-shedding capability and pad-friendly surface that separate premium braking hardware from standard OEM replacements.
