What is the benefit of a two-piece rotor design?

A two-piece rotor design separates the friction ring from the center hub. This allows for weight reduction and, importantly, lets you replace just the worn friction ring while reusing the center hub and bobbins, which lowers long-term running costs.

Do these rotors come with everything needed for installation?

These rotors are sold as a set for the rear axle. While they are designed as a direct replacement, it's always recommended to check the manufacturer's instructions for any additional hardware or specific installation requirements.

How do these rotors affect my car's performance?

By reducing unsprung rotational mass, these rotors contribute to sharper steering response, better tire contact with the road, and can even lead to slight improvements in fuel economy and wheel horsepower.

Product Details

If you're looking to get the most out of your 2016-2021 BMW M2 or 2015-2018 BMW M3/M4, these EBC Racing 2-piece SG Racing rear rotors are a solid choice. They're designed to replace your stock rear rotors, offering a significant upgrade in performance by reducing rotational mass. This means your car will feel more responsive when you turn the wheel, your tires will hold the road better, and you might even see a small bump in fuel economy and wheel horsepower.

These rotors are a floating assembly, meaning the vented friction ring is separate from the center hub. This design not only helps shed weight but also makes them more cost-effective in the long run. When the friction ring eventually wears out after a good amount of use, you can simply replace that part and reuse the center hub and stainless steel bobbins. This setup is built to work with Brembo rear brake calipers and features 5 bolt holes with a 370mm diameter and 24mm thickness.

When installing these, remember they are a direct replacement for your factory rear rotors. The two-piece design is a notable upgrade that can make a real difference in how your car feels and performs, especially during spirited driving or track use. You'll be shaving off crucial unsprung rotational weight, which directly translates to a more agile and connected driving experience.
