Product Description

Upgrade the rear braking of your Audi RS5 or RS5 Sportback (2.9 L V6 Turbo Quattro) with the SHW Performance ARX49211 rotor - designed specifically for the B9 chassis (2018-24) and excluding vehicles with ceramic composite brakes. The 330 mm diameter and 22 mm thickness reflect exact OEM dimensions for this rear axle application, enabling a straightforward direct swap without modifications.

Constructed with a high-carbon alloy and precision machined for flatness, this rotor offers enhanced thermal stability and durability under spirited driving or track use. Its lightweight, smooth-face design reduces unsprung mass and rotational inertia compared to heavier OE units, promoting more responsive braking and better overall vehicle dynamics. Ideal for drivers seeking OEM-quality replacement with elevated performance characteristics.

Installation remains simple - remove the old rear rotor, ensure hub mounting surfaces are clean and flat, fit this ARX49211 rotor using the original hardware and torque specifications, and perform standard pad bed-in. Be sure to verify your vehicle does *not* have ceramic composite brakes (as this unit excludes those). This rotor is tailored for performance street or track use where high-quality materials and fitment accuracy matter.
