The Brembo rear GT big brake kit for 2011–2016 528i matches a four-piston cast caliper to a 345×28 mm two-piece rotor to upgrade rear stopping capability. Fitted with slotted Type-1 rotors and red calipers, the kit provides a replacement that improves pedal firmness and rotor heat dispersion for drivers seeking stronger rear braking without modifying core rear suspension components.
