The Brembo GT rear big brake kit for 2015–2018 BMW M3 (excluding CC brakes) pairs a four‑piston rear caliper with a 380 x 28 mm two‑piece cast rotor in slotted Type‑3 form, finished in yellow. Specified for non‑CC brake M3 rear fitment across those years, the assembly combines multi‑piston hardware and a two‑piece rotor design to aid heat management and consistent pad contact at the rear axle.
