StopTech Power Slot 9/07-09 BMW 328 Front Left Slotted Rotor

When you're looking to get more stopping power out of your BMW, especially if you're running higher-friction brake pads or dealing with wet conditions, a slotted rotor like this one from StopTech can make a real difference. This is a direct replacement for your factory front left rotor, designed to work with your stock calipers. It's built with high carbon metallurgy, which helps reduce noise and resist cracking under stress, and features a black e-coating on the non-friction surfaces to keep rust at bay.

The unique slotting pattern on this rotor isn't just for looks; it actively helps to disperse heat and brake dust away from the pad surface. This helps prevent glazing, which is when the pad material gets too hot and hardens, reducing its effectiveness. The slots also help to bite into the pad material for improved initial response and better performance in wet weather. StopTech also applies a cryogenic treatment to reduce residual stress within the rotor, further improving its resistance to cracking.

This rotor is a solid option for many BMW models from the 2007 to 2021 model years, including popular vehicles like the 328i, 428i, and 228i. It's a well-built component that offers improved braking performance and durability over a standard factory rotor.
