The Brembo big brake kit for 2006–2009 Porsche 997.1 GT3 is a rear GT package using four‑piston cast calipers and two‑piece 380×28 slotted Type‑3 rotors in red. Engineered to increase rear stopping power and thermal dissipation, the kit’s larger slotted rotors help maintain bite under repeated braking while the two‑piece design supports easier rotor service and replacement.
