The Brembo GT big brake kit for 2015–2018 BMW M3 models fitted with CC brakes is a front upgrade pairing six-piston cast calipers with two-piece 380×34 mm rotors drilled and finished in yellow. It’s intended to enhance braking consistency and heat control under track or spirited road use, while the two-piece rotor design supports easier servicing and targeted replacement of the rotor ring.
