The Brembo Big Brake Kit for 2002–2005 7-Series (through 3/5 production) rear applications swaps in GT four-piston cast calipers with two-piece 345 x 28 mm slotted rotors in silver. Offered as a rear direct-fit upgrade, the kit uses two-piece rotors and multi-piston calipers to replace factory components and provide larger braking hardware for improved control under load.
