Is this a complete brake rotor or just the replacement ring?

This is a replacement disc ring for a 2-piece floating rotor assembly. You will need the corresponding hat or bell to complete the rotor assembly.

What is the benefit of a floating 2-piece rotor design?

A floating 2-piece design allows the rotor ring to expand and contract independently of the hub with heat. This helps prevent rotor warping and can lead to a more stable brake pedal feel under demanding conditions.

How does the swept grooved finish help?

The swept grooves on the rotor surface help to sweep away dust and gas that can build up between the pad and rotor. This helps maintain consistent friction and braking performance, especially during hard stops.

Product Details

This EBC Racing replacement disc ring is built for the left front of your 2012-2018 BMW M6, specifically for vented floating rotor setups. It measures 400mm in diameter and has a new thickness of 36mm, with a minimum thickness of 34mm, ensuring it works with your existing caliper and pad setup. The swept grooved finish helps keep the rotor surface clean and consistent, which is important for reliable braking, especially during spirited driving.

What sets this rotor apart is its fully-floating 2-piece design, a feature that injects a new level of quality into high-performance braking. This design allows the rotor ring to expand and contract freely with heat, reducing the risk of rotor warping and ensuring a more stable brake pedal feel. It also features 48 curved vanes, which help to efficiently dissipate heat away from the braking surface, keeping your brakes cooler under load.

This is a replacement ring for a 2-piece rotor assembly. Make sure you are replacing just the rotor ring and not the entire rotor assembly. This part is designed to fit specific M6 models from 2012 to 2018, as well as certain M2 and M5 models.
