The Brembo front GT big brake kit for 1978–1979 Porsche 930 is a front GT upgrade with 6‑piston cast calipers and two‑piece 355×32 mm Type‑1 slotted rotors in silver. Designed for 930 front fitment, this BBK enlarges rotor diameter and adds multi‑piston clamping to improve braking consistency and heat control for spirited driving, while the two‑piece rotor design keeps service and rotor replacement more manageable.
