The Brembo GT rear big brake kit suits 1978–1979 and 1980–1989 Porsche 930 rear applications. It matches cast four-piston calipers with two-piece 345 x 28 mm slotted Type 3 rotors in red, supplying larger rotors and a multi-piston caliper layout for increased rear braking capacity. The kit upgrades the 930 rear system with Brembo two-piece slotted rotors and a red finish.
