EBC Racing 2021+ BMW M3/M4 (G80/G82/G87) (w/o Carbon Ceramic Brakes) 2 Piece SG Racing Front Rotors

When you're pushing your 2021-2022 BMW M3 or M4 hard, especially on the track, reducing unsprung rotational mass is key to unlocking its full potential. These EBC SG Racing 2-piece front rotors are designed specifically for that purpose. By shedding weight from the front wheels, you'll notice a sharper turn-in response, better tire contact with the road, and even a slight improvement in wheel horsepower.

What sets these apart is the 2-piece floating design. The vented iron friction ring is attached to a stainless steel center hub with stainless steel bobbins. This floating design allows the rotor to expand and contract freely with heat, which helps prevent warping and cracking under extreme conditions. Plus, when the friction surface eventually wears out after many miles of use, you can simply replace the outer ring and keep the reusable center hub and bobbins. This significantly lowers the long-term running costs compared to traditional one-piece rotors.

This set is for the front axle and features 380mm diameter vented discs with a 36/34mm thickness. They are a direct replacement for your factory rotors, assuming your M3 or M4 did not come equipped with the optional carbon ceramic brakes from the factory. You'll be re-using your existing calipers and hardware, making for a straightforward installation.
