The Brembo rear brake kit for 2006–2012 BMW 325i (excluding xDrive) replaces the stock rear hardware with a GTS four-piston caliper and cast two-piece 345 x 28 mm drilled rotors in black. This rear BBK improves brake bite and thermal management, offering a serviceable two-piece rotor design that helps maintain consistent braking under aggressive use while matching the vehicle’s original fitment.
