A Brembo GT big brake system built for the BMW I5 M60 xDrive (G60), 2025 onwards, front axle. The discs are 405x34mm 2-piece.
GT|BM calipers are Brembo’s newest upgrade caliper. They are cast using a 4D process that puts the fluid passages inside the caliper body and hides the bleed screw, so there are no external pipes to catch or damage.
Six piston caliper, the usual choice for a performance saloon or coupe front axle.
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.
What is in the kit: 6 piston aluminium calipers, 405mm 2-piece discs with bells, Brembo pads, caliper mounting brackets, braided brake lines and the fitting hardware. Contents vary slightly by application, so check the part number against the list below.
Part numbers
| Disc face | Base part | Full part number by finish |
|---|---|---|
| Cross-drilled | 1T19512A | – |
| Slotted Type 3 | 1T39512A | – |
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 405mm 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.
