R1 91-99 BMW 323I Rear Right Drilled & Slotted Black Brake Rotor

These R1 Concepts brake rotors feature a black electro-coating that helps prevent rust and corrosion, especially around the hub and edges. The drilled holes and slots work together to help vent heat and gases away from the braking surface. This means you get more consistent stopping power, particularly during repeated hard braking situations. This rotor is designed to fit a range of BMW 3 Series models from the early 90s to the end of the decade, including popular cars like the 318i, 325i, and 328i.

The combination of drilled holes and slots offers a practical benefit: the holes help break up gas buildup and allow heat to escape, while the slots sweep away dust and debris. This design helps maintain a cleaner braking surface and can lead to improved pad life compared to plain rotors. It's a solid option if you're looking for an updated look and improved performance over standard factory rotors for your BMW.
