Brembo 08-13 135i Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-1-Silver

This is the Brembo GT Big Brake Kit for the rear of your 2008-2013 BMW 135i. It's a complete system designed to significantly upgrade your braking performance, giving you more confidence when you need to slow down quickly. Brembo is well-known for their high-performance braking components, and this kit represents their top-tier offering for this specific BMW model.

The kit includes a pair of 4-piston GT calipers, which are cast from aluminum for a good balance of strength and light weight. These calipers work with 345x28mm two-piece rotors that are slotted. The slots on the rotor surface help to vent gases and dust away from the pad surface, which keeps the braking consistent even under heavy use. The calipers themselves are finished in a clean silver color, and the two-piece rotor design allows for better heat management and easier replacement of just the rotor ring if needed down the line. This kit is designed as a direct replacement for your factory brake system, meaning it bolts on without major modifications, though professional installation is recommended given the complexity of brake systems.

When you're pushing your 135i hard, whether on the street or the track, having a braking system that can keep up is crucial. This Brembo GT BBK is built to handle that demand, offering improved stopping distances and fade resistance compared to the stock setup. It's a substantial upgrade that makes a real difference in how your car feels and performs under braking.
