Carbon Ceramic Rotor Upgrade Kit (Rear) | B9/B9.5 RS5 (Comp Package) | ICOOH Braking Systems

Overview

Upgrade the rear braking system on your Audi B9/B9.5 RS5 Competition with the ICOOH Rear Carbon Ceramic Brake Conversion Kit. Designed for RS5 models equipped with the factory front Carbon Ceramic Brake (CCB) package, this kit replaces the OEM iron rear rotors and pads with a lightweight carbon ceramic setup engineered to complement the factory front CCB system.

The ICOOH rear carbon ceramic rotors are available in two different carbon constructions: Short Chopped Carbon and Long Carbon. Choosing the correct construction is important, as each is optimized for a different type of driving. Short Chopped Carbon is the recommended choice for primarily street-driven vehicles, while Long Carbon is designed for the increased thermal demands of track and competition use.

Short Chopped Carbon — Street & Performance Driving

The Short Chopped Carbon construction is the ideal choice for street-driven RS5s, including vehicles used for spirited driving and occasional high-performance use. Its chopped carbon fiber composition provides excellent braking performance, thermal stability, and durability while maintaining the benefits of a lightweight carbon ceramic rotor.

• Recommended for: Daily driving, street performance, spirited driving, and occasional aggressive use
• Best balance: Performance, durability, comfort, and street usability
• Ideal for: Vehicles that see the majority of their use on public roads

Long Carbon — Track & Competition

The Long Carbon construction is designed for vehicles subjected to sustained high-temperature braking and repeated heavy braking events. The longer carbon fiber construction is better suited to the extreme thermal demands encountered during track driving and competition use.

• Recommended for: Track days, circuit driving, racing, and competition use
• Designed for: Sustained high-temperature braking and repeated heavy braking events
• Ideal for: Vehicles that regularly experience demanding track conditions

Which Carbon Construction Should I Choose?

For most street-driven RS5s, we recommend the Short Chopped Carbon option. It provides an excellent balance of performance, durability, and everyday usability while offering the weight and thermal benefits of a carbon ceramic rotor.

If your RS5 regularly sees track days, circuit driving, or competition use, the Long Carbon option is the better choice. Its construction is intended to withstand the sustained heat and repeated high-energy braking associated with demanding track conditions.

Fitment

This conversion kit is designed for vehicles equipped with the factory front Carbon Ceramic Brake package and replaces the OEM iron rear brake system. Confirm that your vehicle is equipped with the factory front CCB system before ordering.

Note: Short Chopped Carbon and Long Carbon are different rotor construction options intended for different driving applications. Select the appropriate configuration based on how the vehicle will be used.
