The Brembo rear GT big brake kit for 2006 330i matches a four-piston cast caliper to a 345×28 mm two-piece rotor to improve rear braking duty. Equipped with slotted Type-1 rotors and yellow calipers, this upgrade offers a stronger, more consistent pedal feel and better rotor ventilation for spirited driving without requiring changes to rear suspension geometry.
