The Brembo GT rear big brake kit for 2012–2017 M5 (F10) applications installs cast 4-piston rear calipers and two-piece 380x28mm slotted Type1 rotors in black. Intended as a rear axle upgrade, it pairs larger calipers with slotted two-piece rotors to refresh braking hardware and offer a subtle black-caliper appearance for compatible F10 rear hubs.
