The Brembo rear big brake kit for 2006–2009 Porsche 997.1 GT3 and GT3RS (excluding PCCB) upgrades the rear brakes with four-piston billet calipers and two-piece 380×28 mm rotors. This variant uses slotted Type 1 rotors with a nickel finish, presenting a billet caliper and 2pc rotor combination as a direct rear braking replacement for those GT3/GT3RS models.
