Rear discs on a heavy quattro

The B9 RS cars carry serious mass and put meaningful braking through the rear axle. Slots clear gas and pad material out of the contact patch under repeated hard stops, holding the rear friction level steady so the car stays settled under braking rather than pushing everything onto the front.

Rotors only

Pads are not included. Fit fresh rear pads alongside the new discs where practical, and run a full bed-in cycle so the pad material lays down evenly before the car sees track heat.

Fitment

Listed for the 2017+ Audi RS4 and RS5 (B9), rear axle. Confirm fitment by year, trim, and brake package before ordering.
