The Brembo GTS front big brake kit for 1999–2005 BMW 330i (excluding xDrive) features six‑piston calipers and cast two‑piece 355x32 slotted Type‑3 rotors in black. This configuration increases rotor area and piston clamping over many OE systems to improve braking response and heat control, with the two‑piece rotor layout providing improved thermal behavior and easier serviceability.
