The Brembo GT rear big brake kit for 2006–2012 BMW 325i (excluding xDrive) features four-piston cast calipers and two-piece 345 x 28 mm slotted rotors in a Type‑3 silver finish. Built as a direct rear replacement, its larger two-piece rotor design and multi-piston calipers offer improved braking control and thermal management compared with standard hardware without altering the vehicle's original mounting.
