Rotor 8bt .350in 11.44in 7in Rear Drag

The Wilwood Rotor 8bt .350in 11.44in 7in Rear Drag is a premium drilled brake rotor engineered for high-performance braking systems where thermal management and fade resistance are critical. With an 11.438-inch outer diameter, 0.350-inch thickness, and 8 x 7.000-inch bolt pattern, this rotor delivers the robust stopping geometry needed for vehicles running serious suspension and powertrain upgrades. The drilled design reduces unsprung weight while improving brake fluid heat dissipation—a proven advantage in extended braking scenarios on track or during heavy hauling operations.

Constructed from steel and finished in black oxide, this Wilwood rear rotor resists corrosion and provides excellent durability in both street and performance environments. The 0.350-inch thickness is the industry standard for rear rotors running dual-piston or high-output calipers, allowing consistent pad contact pressure without deflection under load. The 8-bolt hub pattern ensures compatibility with modern truck and performance vehicle brake systems. Each unit weighs 5.04 lbs and ships ready to install—no additional machining required for vehicles engineered around Wilwood's OEM-matching specifications.

This rear rotor is ideal for truck owners, off-road enthusiasts, and performance builders upgrading from OEM hardware. Whether managing sustained downhill braking on mountain passes, towing heavy loads, or improving stopping power in a lifted or turbocharged platform, the Wilwood 160-1601 rotor provides the thermal capacity and structural integrity necessary for daily-driven builds that demand more from their braking systems than factory components can deliver. Buyers integrating Wilwood's modular brake kits will find this rotor a direct match for both geometry and performance targets.
