StopTech Sport Drilled & Slotted Rear Left Brake Rotor

Improve your BMW's braking performance with the StopTech Sport Drilled & Slotted Rear Left Brake Rotor. Engineered as a direct replacement for your factory brake disc, this rotor offers enhanced stopping power and superior heat management. It's designed to integrate seamlessly with your existing brake system, providing a noticeable upgrade in braking responsiveness and reliability for a more secure driving experience.

Key Features and Benefits:

  • Advanced Cooling System: The precise drilling and slotting pattern effectively dissipates heat and expels brake dust, preventing overheating and maintaining optimal performance under stress.
  • Consistent Braking Power: Slotting ensures a clean pad surface for consistent contact, improving braking bite and responsiveness in various conditions, from dry to wet weather.
  • Durable E-Coating: A protective black e-coating shields the rotor from corrosion and rust, ensuring long-term durability and a clean appearance behind your wheels.
  • Quieter Operation: With high-carbon metallurgy (in most applications), these rotors are engineered for reduced noise and vibration, offering a more comfortable ride.
  • Direct Fit Design: This 1-piece rotor is designed for a direct fit, making installation simple and eliminating the need for vehicle modifications.

This StopTech Sport Drilled & Slotted Rear Left Brake Rotor is suitable for a range of BMW models, including the 228i, 228i xDrive, 230i, 230i xDrive, 320i, 320i xDrive, 428i, 428i Gran Coupe, 428i xDrive, M235i, and M235i xDrive.
