AeroRotor Ring

The StopTech 31.C56.1102.01 is an AeroRotor Ring, a high-performance, two-piece replacement friction ring designed for the right side of a vehicle's braking system within a StopTech Big Brake Kit. It measures 343mm in diameter and 30mm in thickness and features a slotted surface. This design helps to improve braking performance by continually cleaning the pad surface, removing dust and friction material, and maintaining optimal pad-to-rotor contact. AeroRotors are engineered with patented internal cooling vanes that significantly increase airflow, leading to better heat dissipation and reduced brake fade, especially under demanding conditions. The two-piece construction, typically with a billet aluminum AeroHat (transferable from the original disc), contributes to a lighter assembly, which can improve acceleration, deceleration, and overall handling. StopTech AeroRotors are 100% made in the USA.
