Audi RS4 B9 Rear Carbon Ceramic Brake Kit

Fitment and Compatibility

This rear carbon ceramic brake kit fits the Audi RS4 B9. Confirm your RS4 is the B9 generation and originally equipped with (or compatible with) carbon ceramic brakes before ordering, since carbon ceramic rotors require matching caliper and mounting hardware that isn’t interchangeable with standard steel rotor setups.

Part Overview

Carbon ceramic brakes are a premium factory option on the RS4 B9, offering significantly reduced weight and better fade resistance under repeated hard braking compared to standard steel rotors, at a considerable price premium reflecting the material cost.

Condition and What’s Included

Inspected for rotor wear, surface condition, and caliper integrity before listing — carbon ceramic rotors wear differently than steel and should be assessed by someone familiar with this rotor type, which we’ve done before listing.

Installation Notes

Requires confirming your car’s brake system is originally equipped for or compatible with carbon ceramic rotors before installation — this isn’t a simple swap onto a standard steel-brake RS4 without additional compatible hardware.

OEM vs Aftermarket

Given the premium and safety-critical nature of carbon ceramic brakes, genuine OEM sourcing is strongly recommended over aftermarket carbon ceramic alternatives, which have a much less established track record for material quality and heat cycling durability.
