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 high-performance slotted brake rotor engineered for vehicles demanding precise thermal management and consistent stopping power. This right-hand rotor features an 11.750-inch outer diameter with 0.99-inch thickness, designed to handle demanding driving conditions where fade resistance and rapid heat dissipation are critical. The slotted design actively removes gas and debris from the pad interface, maintaining optimal friction and extending rotor life under sustained braking loads.

Constructed from cast iron in a natural finish, this Wilwood rotor is engineered to standard specifications with an 8 x 7.00-inch bolt pattern and 16-vane internal cooling geometry. The vane configuration accelerates heat transfer away from the friction surface, preventing thermal buildup that causes brake fade during aggressive driving, towing, or high-performance applications. The 7.22-pound weight and precise dimensional tolerances ensure compatibility with OEM and aftermarket brake systems designed for this specification. Slot geometry reduces pad glazing and promotes consistent bite across the entire brake pad sweep.

This rotor is suitable for passenger vehicle applications where OEM brake performance needs reinforcement during towing, mountain driving, or high-temperature use. Drivers upgrading from solid rotors to slotted designs often see improved modulation and shorter stopping distances when paired with quality brake pads. The right-hand designation indicates this rotor's orientation for specific mounting positions; verify bolt pattern and vehicle compatibility before ordering to ensure proper fitment.

Slotted rotors are a proven choice for applications where standard solid rotors cannot consistently manage heat energy. The Spec-37 series from Wilwood represents the balance between performance gains and real-world durability, avoiding the extreme wear characteristics of cross-drilled designs while delivering the thermal advantages operators expect from premium brake hardware.
