Fitment

Listed for the Audi B9 chassis S4, S5 and SQ5. The source does not break the application down by model year and does not state a rotor diameter, so confirm fitment by year, trim, and brake package before ordering - measure your current front rotor if you are unsure.

Why slotted rotors

Slots break up the layer of gas and pad debris that builds between the friction surface and the pad under hard use, so the pad face stays clean and the bite stays consistent through repeated heavy stops. They also give a simple visual wear check: once the slot edges begin to fade away, the disc is near the end of its service life.

Installation notes

Replace rotors as an axle pair and fit fresh pads at the same time so both sides wear evenly. Bed the new brakes in with a series of progressively firmer stops from moderate speed before any hard or track driving, and re-check the wheel fasteners after the first drive.
