StopTech Sport Drilled & Slotted Rotor - Rear Left

If you're looking to get more out of your BMW's braking system, consider these StopTech Sport Drilled and Slotted Rotors. They're designed as a direct replacement for your factory rear left rotor, fitting a range of BMW 3 Series and 4 Series models like the 335i, 340i, 435i, and 440i. These rotors aren't just about looks; they're built to offer a noticeable improvement in braking performance, especially when paired with performance brake pads.

What sets these rotors apart is the combination of cross-drilling and slotting. The holes help dissipate heat and brake dust, preventing the pads from glazing over, while the slots help clear away gases and moisture. This means you get a more consistent and confident bite, whether you're braking hard or in wet conditions. The rotor itself is constructed with high-carbon metallurgy, which helps reduce noise and resist cracking from thermal stress. Plus, the black e-coating on the non-friction surfaces protects against corrosion, keeping your rotors looking good behind your wheels.

These are a solid option if you want to upgrade your braking performance and appearance. They install like your stock rotors, making the job straightforward for a mechanic.
