What material are these EBC rotors made from?

These EBC RK Series rear rotors are manufactured from G3000 Grey iron. This material is chosen for its balance of strength and heat handling capabilities, suitable for OE-style replacement parts.

What is the purpose of the Thermic coating on these rotors?

The Thermic coating on these rotors serves two main purposes. It provides a clean, impressive finish and also offers corrosion resistance, helping to protect the rotor from rust and environmental damage.

Are these rotors sold individually or as a set?

The product description indicates a 'Disc Brake Rotor Set' and 'Riveted Disc Set', suggesting these rotors are sold as a pair for the rear axle.

About this part

Product Details

Using G3000 Grey iron, these EBC RK Series rear rotors are built to match the original equipment specifications for your vehicle. They feature a vented design, meaning there are internal passages to help dissipate heat, which is crucial for consistent braking performance, especially under load. The rotors measure 330mm in diameter, are 20mm thick, and have a 64mm height, with 5 bolt holes for secure mounting.

These rotors are constructed with EBC's riveted disc style, which helps prevent rotor distortion and noise. They also come with a Thermic coating. This coating not only gives the rotors an impressive finish but also provides corrosion resistance, helping to keep them looking good and performing well over time. This makes them a solid option for drivers who want reliable rear braking performance that holds up.

This set is designed to fit a range of BMW and Toyota models, including the BMW X3, X4, Z4, and various 3-series and 4-series Gran Coupe and xDrive variants, as well as the Toyota GR Supra. They are intended for use with FMSI Pad No. D2221, so be sure to check your pad compatibility when ordering.
