The Brembo Rear GT big brake kit for 2015–2018 BMW M3 with carbon‑ceramic brake equipment replaces the rear system with a four‑piston caliper and 380×28 mm two‑piece cast rotors. The kit uses slotted Type 3 rotors and yellow finished calipers, supplied as a vehicle‑specific rear brake assembly and intended to match the original rear braking architecture for those model years.
