Brembo 99-05 330i (Excl. xDrive) Rr GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Slotted Type3-Silver

This is the Brembo rear GT Big Brake Kit for your 1999-2005 BMW 330i, specifically excluding the xDrive models. If you're looking to significantly upgrade your braking performance, especially for spirited driving or track use, this kit is designed to make a substantial difference. It replaces your factory rear brake components with a much more robust setup, featuring larger rotors and powerful calipers that work together to handle heat and provide more consistent stopping power.

At the heart of this kit are the 4-piston cast aluminum calipers, which offer increased clamping force over stock. These calipers grip 345x28mm two-piece rotors. The two-piece design allows the rotor and hat to expand and contract independently, which helps manage heat and reduce the risk of warping. The rotors themselves are slotted with Brembo's Type 3 pattern, which helps to vent gases and dust away from the pad surface, maintaining optimal friction and preventing fade during hard braking. The silver finish on the calipers adds a clean, performance-oriented look to your vehicle's rear end.

This kit is a comprehensive upgrade, meaning it includes everything you need to install the new calipers and rotors. While it's a direct fit for the specified 330i models, it's always a good idea to consult the included installation manual for specific torque values and procedures. Upgrading your rear brakes with a kit like this can help balance your vehicle's braking system, especially if you've already upgraded the front brakes, leading to a more predictable and confident driving experience.
