The SHW ARX44218 is a drilled-dimpled lightweight rear brake rotor for 2008-2012 Audi R8 4.2L (Excl Ceramic Brakes). It measures 356 x 32 mm, weighs 8.7 kg, and is made in Germany. SHW lists OEM reference 420615601F for this application. It is a straightforward vehicle-specific replacement choice for a brake refresh when you want the correct rotor position, dimensions, and configuration clearly identified.
If the existing disc is worn, scored, heat-checked, damaged, or otherwise due for replacement, confirming the correct rotor specification is an important part of the brake service. This SHW rotor is specified with lightweight construction, a drilled-dimpled friction surface and a round rotor profile. Verify the detailed fitment, axle/side, rotor size, and OEM reference before ordering, especially on vehicles offered with multiple brake or wheel packages.
