Product Description

The EBC RK1861 is a high-quality, direct-fit rear brake rotor ideal for a range of 2.0 L BMW models. Built from durable G3000 grey-iron and featuring a thermic anti-rust coating, it offers both reliability and corrosion resistance under real driving conditions.

With a 300 mm diameter and 20 mm thickness, it matches OEM specifications precisely, so you can install it using your factory hardware without any modification. The vented design helps dissipate heat more effectively, reducing the risk of brake fade during repeated use.

Whether you're replacing worn-out OEM rotors or upgrading for improved longevity and reliability, the RK1861 provides a sensible, value-oriented solution - especially for daily driving. Make sure to check rotor thickness both before and after installation, torque the mounting bolts to spec, and follow a proper bedding-in procedure for optimal performance.
