StopTech Sport Slotted Rotor - Rear Left

This is the StopTech Sport Slotted Rear Left Rotor, a direct replacement for your factory brake discs. It's designed to work with your stock calipers and fits a wide variety of BMW models, including the 2013-2018 BMW 320i xDrive, 2014-2018 BMW 328d xDrive, and 2017-2020 BMW 430i Gran Coupe. If you're looking to improve your car's stopping power and get a more aggressive look behind your wheels, this rotor is a solid option.

What sets these rotors apart is the unique slotting pattern. These slots help to disperse heat and brake dust, which prevents pad glazing and gives you a more consistent bite. This means better braking performance, especially in wet conditions. The rotor also features a black E-coating on the non-friction surfaces to protect against corrosion, and the high carbon metallurgy helps reduce noise and resist cracking from thermal stress. This makes for a well-built rotor that's designed to last.

Because these are direct OE replacements, installation is straightforward. You'll notice an improved initial bite and better response, especially when paired with higher-friction brake pads.
