The EBC GD7612 is a front rotor set from the brand's GD Sport line, sized at 340 x 30 mm for the 2.0T Audi S3 8V. Each disc is cast from grey iron at EBC's UK foundry and combines a dimpled face with wide-aperture slots. The dimples let pad gases escape without through-drilled holes, which can promote cracking, while the slots sweep away debris and draw cooling air across the pad contact area.
Stock discs handle commuting well, but this set targets drivers who face repeated hard stops on canyon roads, track days, or spirited mountain runs. The slotted face is designed to limit brake fade under load and keep dust out of the braking zone. Compared with plain-faced aftermarket blanks, the reason to spend more is the GD Sport slot-and-dimple pattern combined with EBC's quality control. Check the finish on arrival, since coating appearance has varied between production batches.
Published fitment for this rotor lists 2015 to 2020 S3 8V models, while some listings begin at 2014, so verify the application against your VIN before ordering. The same rotor pattern is shared with several other VW and Audi applications, which makes it important to confirm the S3 8V listing rather than assume a match from the part number alone. Searching for "8V S3 GD7612 front rotors," "340mm slotted dimpled S3 brake upgrade," or "EBC GD Sport S3 track rotors" will surface the correct application data.

Owners on user forums report that bleeding is unnecessary unless the brake line is opened or the pedal feels soft. Old fluid that needs flushing is the other reason to bleed.
Owners on user forums describe the front rotor swap on the 8V S3 as a manageable job for a home mechanic with basic hand tools. The usual sequence is to remove the wheel, undo the caliper bolts, hang the caliper on wire so the hose is not stressed, remove the rotor retaining screw with a T-30 socket, clean corrosion off the hub face, and compress the caliper piston with a C-clamp before refitting. Keep the brake line from being pinched while the caliper is moved, and watch the fluid reservoir, which can overflow as the piston goes back. Replacing pads at the same time is the common practice, and the new pads should be bedded in according to their maker's procedure.
