The Brembo GT big brake kit is a direct-fit front upgrade combining a four-piston cast caliper with two-piece 355 x 32 mm slotted Type 1 rotors, finished in silver. Supplied as a matched caliper-and-rotor set, it replaces factory front components on 2006–2012 325i (excluding xDrive) applications. The two-piece rotor design eases maintenance and permits rotor replacement without disassembling the caliper carrier.
