Brembo 06-12 325i/328i (Excl. xDrive) Rear GT BBK 4 Pist Cast 345x28 2pc Rotor Slotted Type3-Silver

This Brembo GT Big Brake Kit uses a 345x28mm two-piece rotor design, a solid foundation for improved stopping power on your BMW. The calipers feature a four-piston cast aluminum construction, offering a strong and lightweight setup that works to reduce unsprung mass. This kit is specifically designed for the rear of your 2006-2012 325i or 328i, excluding xDrive models, to ensure a direct fit and optimal performance.

The two-piece rotor construction allows for better heat dissipation compared to a single-piece rotor, as the aluminum hat can shed heat more effectively. The rotors themselves are slotted, which helps to clear out brake dust and gases that can build up between the pad and rotor surface, maintaining consistent braking performance even under heavy use. The cast aluminum calipers are built to house larger brake pads, which increases the surface area for friction and further enhances stopping capability. This kit is a significant upgrade over the factory braking system, aimed at drivers who demand more from their vehicle's performance.

When installing this kit, you'll want to ensure you have the necessary tools and a good understanding of brake system components. It's always a good idea to consult the manufacturer's installation guide for specific torque values and procedures. This kit is a substantial investment in your vehicle's braking system, and proper installation is key to realizing its full potential. Consider flushing and replacing your brake fluid with a high-performance DOT 4 fluid to complement the new hardware.
