AEROROTOR RING + HARDWARE

This replacement 380x32mm Drilled Left brake rotor is designed for StopTech Big Brake Kits. It serves as a friction ring to restore the performance of StopTech two-piece rotor assemblies. Engineered with StopTech’s advanced AeroRotor internal vane design, it significantly improves airflow and cooling efficiency to reduce heat buildup, brake fade, and rotor warping during aggressive driving or track use.

The rotor features high-carbon metallurgy for enhanced strength and durability under extreme conditions. While specific coating details for this MPN were not explicitly found, similar StopTech AeroRotors often feature a corrosion-resistant zinc coating for longevity and appearance. The dimensions are precisely 380mm in diameter and 32mm in thickness, ensuring a direct fit within compatible StopTech Big Brake Kits. Hardware is included for a complete replacement.

Installation requires disassembling the existing StopTech two-piece rotor assembly to replace the friction ring. Re-use of the existing hat and mounting hardware (excluding the friction ring) is expected. Proper torque specifications should be followed for reassembly to ensure safety and performance. This part is a component of a larger brake system and is not intended for standalone installation on a vehicle without a compatible StopTech Big Brake Kit.

This specific part is a replacement for a component within a StopTech Big Brake Kit, rather than a direct-fit part for individual vehicles. Therefore, compatibility hinges on the particular StopTech Big Brake Kit it is intended for. It is crucial to verify this part number (31.836.5201.01) against the documentation or specifications of your existing StopTech Big Brake Kit, especially ensuring the correct diameter, thickness, drilling pattern, and left-side orientation for proper fitment and braking performance. This rotor is not compatible with OEM brake systems.

StopTech AeroRotors are known for their performance in demanding applications, offering superior thermal management and consistent brake feel. This replacement ring maintains that standard, ensuring your big brake kit continues to deliver optimal stopping power and reliability.
