Brembo 06-12 325i (Excl. xDrive) Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type3-Black

Brembo is a name many performance enthusiasts trust for stopping power, and this Rear GT Big Brake Kit is a prime example of their work. This kit is designed to give your 2006-2012 BMW 325i (excluding xDrive models) a serious upgrade in braking performance, especially if you're looking to handle more demanding driving conditions or simply want a more responsive pedal feel. It replaces your factory rear brakes with a robust 4-piston caliper system and larger, two-piece rotors.

At the heart of this kit are the 4-piston calipers, cast from durable materials for strength and rigidity. These calipers clamp down on 345x28mm two-piece rotors. The rotors are slotted with Brembo's Type 3 pattern, which helps to vent gases and heat away from the braking surface. This venting action is crucial for maintaining consistent stopping power, especially during repeated hard braking, as it helps prevent brake fade. The two-piece rotor design also helps manage heat and can make future rotor replacements more straightforward.

This kit is a significant upgrade over stock, offering improved thermal capacity and a more direct pedal feel. When installing a big brake kit like this, it's always a good idea to consult the manufacturer's installation guide for specific torque values and procedures. While this kit focuses on the rear, it's designed to work effectively with your vehicle's existing front braking system, providing a balanced braking experience.
