The Brembo GT rear big brake kit for 2015–2018 M3 (excl. CC brakes) applications installs cast 4-piston rear calipers and two-piece 380x28mm slotted Type3 rotors in a red finish. The kit enlarges braking hardware at the rear and pairs it with slotted rotors to maintain pad contact and shed surface debris while providing a bold red-caliper look.
