A Brembo GT disc kit built for the Audi RS3 (8V), 2015 to 2020, front axle. The discs are 380x34mm 2-piece.
This is a disc kit rather than a full conversion. It replaces the original discs and works with the calipers already on the car.
Disc face: available cross-drilled or Type 3 slotted. Type 3 slots are the pattern Brembo uses in professional motorsport. They give a strong initial bite and keep the pad face clean as it beds in.
Fitment notes from Brembo: This system includes oversized 2-Piece disc assemblies, brackets, and hardware to be used with the OEM calipers.
What is in the kit: 380mm two piece disc assemblies with bells and the mounting hardware. Calipers and pads are not included unless a fitment note above says otherwise.
Part numbers
| Disc face | Base part | Full part number by finish |
|---|---|---|
| Cross-drilled | 1019028A | – |
| Slotted Type 3 | 1039028A | – |
The last character sets the caliper finish or the line. 1 is black, 2 red, 3 silver, 4 gold, 5 yellow, 6 white, 7 fluorescent yellow. S is a GT-S caliper and R is a GT-R caliper.
Wheel clearance is the thing to check first. A 380mm disc with this caliper needs a specific wheel offset and spoke shape, and the requirement for a GT-R caliper is different from the GT version. Send us your wheel size, offset and make and we will read the clearance drawing against it before anything is ordered.

Brake work is safety critical. Brembo asks that these systems are installed by a qualified technician, and the kit must be checked, bled and road tested to the instructions supplied with it before the car is driven.
