Do I need to replace both left and right rear rotors at the same time?

It is generally recommended to replace brake rotors in pairs (left and right) to ensure even braking performance. While this listing is for the left rear rotor, you should consider purchasing the corresponding right rear rotor as well.

What is the benefit of cross-drilled rotors?

Cross-drilled rotors have holes that allow hot gases and dust generated during braking to escape from the rotor surface. This helps prevent brake fade and maintain more consistent stopping power, especially during spirited driving or heavy braking.

Does this rotor come with new hardware?

This product listing is for the brake rotor only. New brake hardware, such as caliper bolts or mounting screws, is typically sold separately and should be inspected or replaced when installing new rotors.

Product Details

If you're looking to maintain or improve the braking performance on your 2021-2025 BMW M3 or 2021-2022 BMW M4, this left rear brake rotor from SHW Performance is a solid option. It's specifically designed for the rear axle, ensuring it works correctly with your vehicle's braking system.

This rotor features cross-drilling, which helps to vent hot gases and dust away from the braking surface. This process aids in keeping the rotor cooler during hard braking, which can lead to more consistent stopping power. Being a lightweight rotor, it also helps reduce unsprung weight, potentially offering a small benefit to handling. SHW Performance is known for making well-built brake components, and this rotor is no exception, offering a good balance of performance and durability for your M-series BMW.

When replacing brake rotors, it's always a good idea to inspect your brake pads and hardware at the same time. Ensure you follow the manufacturer's recommended procedures for installation to get the most out of these rotors.
