SHW 21-22 Audi RS6 4.0L V8 Rear Drilled-Dimpled Lightweight Brake Rotor (4K0615601A)

  • Up to 50% better cooling to prevent brake fade

Upgrade the braking performance of your high-performance Audi with the SHW Performance ARX40483 rear drilled-dimpled lightweight brake rotor. Designed as a direct-fit replacement for the original 4K0615601A application, this rotor is engineered for select Audi RS models equipped with the 4.0L V8 engine. Its performance-focused design helps improve heat management during demanding street or spirited driving conditions.

The drilled and dimpled surface promotes more effective cooling and helps reduce the risk of brake fade by allowing heat and gases to dissipate more efficiently from the braking surface. Compared with a conventional rotor, the lightweight construction can help reduce unsprung and rotating mass, supporting responsive handling and consistent braking feel. SHW Performance manufactures this rotor for drivers who want dependable braking performance without unnecessary weight.

This rear brake rotor fits select 2020–2023 Audi RS Q8, 2021–2022 Audi RS6 Avant, and 2021–2023 Audi RS7 Sportback applications. Verify vehicle fitment and the original equipment part number before ordering to ensure proper compatibility. The SHW Performance ARX40483 is sold as an individual rotor and is intended for replacement of the corresponding rear rotor on compatible vehicles.
