Brembo 12-15 335i xDrive Exc MSport Brakes Rr GTS BBK 4Pis Cast 345x28 2pc Rtr Slot Type3-Black HA

The cast iron calipers in this Brembo rear brake kit are designed with four pistons, each measuring 345mm in diameter and 28mm thick for the rotors. This setup is built for the 2012 through 2015 BMW 335i xDrive models, specifically excluding the M Sport package. The two-piece rotor design helps manage heat more effectively than a single-piece rotor, and the Type 3 slotting pattern on the rotors is chosen for its ability to help clear dust and gas away from the pad surface, which can improve braking consistency under demanding use.

This kit includes Brembo's GTS calipers, which are a popular choice for drivers looking for a significant upgrade over stock braking components. The calipers themselves are finished in black, offering a clean look behind your wheels. The two-piece rotors are constructed from a high-carbon cast iron for the braking surface, paired with an aluminum hat to reduce unsprung weight and further aid in heat dissipation. This combination is intended to provide more reliable stopping power and better fade resistance compared to factory brakes, especially during spirited driving or repeated hard braking events.

When installing this big brake kit, it's important to note that it is designed as a rear upgrade. You'll want to ensure your front brakes are also up to the task, or consider a matching front kit if you're aiming for a complete system overhaul. Always refer to the manufacturer's installation instructions for specific details regarding fitment and any necessary modifications or hardware.
