Audi RS4 B7 4.2 Rear Heat-Treated Upgraded Performance Slotted Rotors – 324mm

Audi RS4 B7 4.2 Rear Performance Brake Rotors

Developed specifically for the Audi RS4 4.2 V8 B7 (2005–2008), these 324 mm heat-treated rear performance slotted rotors provide a high-quality alternative to standard factory replacement discs for drivers who want improved thermal stability, dependable braking performance and a complete ready-to-fit 2-piece disc assembly.

Each disc uses a 2-piece construction with a separate hat/bell and cast-iron friction rotor. Unlike a replacement ring-only option, this rear set is supplied complete with both the hat and rotor, giving RS4 owners a straightforward replacement solution without having to reuse the existing rear disc hats.

Built for heat, stress and repeated braking

The friction rings are heat-treated and precision machined to cope with the high temperatures and repeated braking cycles generated by a performance vehicle such as the RS4 B7. The slotted braking surface helps clean and refresh the brake pad face, assists with consistent pad-to-disc contact and supports stable braking performance during spirited road use.

The vented design improves heat dissipation, while the 2-piece construction separates the friction ring from the hat. This type of construction is commonly used in performance braking applications because it can offer improved thermal management and allows the braking components to be engineered specifically for demanding use.

Why consider this instead of an agent replacement?

Genuine agent brake components can be an excellent factory replacement, but they are often priced at a premium. This Superior Friction performance option gives Audi RS4 B7 owners another route: a vehicle-specific, complete 2-piece rear disc assembly with heat-treated slotted rotors at a clearly published set price.

For owners who enjoy enthusiastic road driving, want an upgraded appearance behind the wheel, or simply want a specialist performance replacement rather than paying solely for an original-equipment branded part, this set offers a practical alternative while retaining the correct RS4-specific dimensions and fitment.
