Sport Drilled/Slotted Br ake Rotor

The Sport Drilled/Slotted Brake Rotor from StopTech is a performance upgrade designed for drivers who demand superior stopping power and heat dissipation during aggressive driving, track use, or daily high-performance operation. This left-side rotor (MPN 127.61112L) is ideal for street enthusiasts, autocross competitors, and drivers running track-focused brake pads that generate higher temperatures than OEM compounds.

Unlike factory solid rotors, this rotor's engineered geometry combines drilled and slotted patterns to address the core thermal and friction challenges that plague stock braking systems under sustained load. The drilled holes promote airflow and aid thermal transfer, while the slots act as escape channels for outgassing and dust particles, preventing glazing that reduces pad bite. This dual-pattern approach extends both rotor and pad life by promoting even wear and lowering operating temperatures.

StopTech's precision manufacturing ensures concentricity and balance, critical for eliminating brake vibration and pulsation that can degrade stopping confidence and driver control. Whether you're upgrading a street car, weekend track machine, or tackling mountain roads, this rotor delivers measurable improvements in fade resistance and pedal feel, making it a reliable choice for high-performance applications.
