Brembo 99-05 330i (Excl. xDrive) Rr GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Slotted Type1-Silver

This is the Brembo GT Big Brake Kit for the rear of your 1999-2005 BMW 330i, specifically excluding xDrive models. This kit is designed to significantly upgrade your braking system, offering improved stopping power and heat management for spirited driving or track use. It features a pair of robust 4-piston calipers and two-piece rotors that are larger than stock, measuring 345mm in diameter and 28mm thick, with a slotted surface designed to help clear heat and dust.

The calipers in this kit are cast from high-strength aluminum, a material chosen for its ability to dissipate heat effectively while keeping weight down. The two-piece rotor design is also a key feature; it separates the braking surface from the hub assembly. This separation allows for independent expansion and contraction due to heat, which helps prevent warping and ensures a more consistent pedal feel. The slotted rotor surfaces are specifically designed to vent gases and debris away from the pad surface, which is crucial for maintaining optimal braking performance under heavy load, like during repeated hard stops on a track or during aggressive canyon driving. The Type 1 silver finish on the calipers offers a clean, performance-oriented look.

When installing a big brake kit like this, it's important to ensure all components are properly fitted and torqued according to Brembo's specifications. This kit is a substantial upgrade, and while it's designed to be a direct fit for the specified models, it's always a good idea to consult the included installation instructions. You'll notice a significant improvement in braking feel and fade resistance compared to the factory setup, giving you more confidence when pushing your 330i.
