Brembo 99-05 323i/325i/328i (Excl. xDrive) Rr GT BBK 2 Pist Cast 2pc 294x19 1pc Rotor Drilled-Black

This Brembo GT Big Brake Kit for the rear of your 1999-2005 BMW 323i, 325i, or 328i (excluding xDrive models) includes everything you need to significantly upgrade your braking system. You get a pair of 2-piston cast iron calipers, two 294x19mm one-piece rotors that are drilled for heat dissipation, and all the necessary hardware to get them installed. This kit is designed to replace your factory rear brakes with a more robust setup, offering improved stopping power and consistency, especially during spirited driving or repeated hard braking.

The calipers in this kit are constructed from cast iron, a strong and reliable material known for its thermal stability and durability under heavy use. The rotors are a 294mm diameter with a 19mm thickness, featuring a drilled surface pattern. Drilling helps to vent gases and heat away from the pad surface, which can lead to more consistent braking performance and reduced fade compared to solid rotors. This one-piece rotor design is a common and effective approach for many performance applications, balancing performance with ease of installation. The 2-piston caliper design offers a good balance of clamping force and pad surface area, working effectively with the included rotor size to enhance your vehicle's braking capabilities.

When installing a big brake kit like this, it's always recommended to consult the manufacturer's installation guide for specific instructions and torque specifications. While this kit is designed as a direct replacement for the factory rear brake components on compatible models, ensuring proper fitment and function is key. You might also consider checking your brake fluid level and condition, as a brake fluid flush is often a good idea when upgrading your braking system to ensure optimal performance from your new Brembo components.
