Brembo 99-04 996 Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Slotted Type3-Silver

If you're looking to significantly upgrade the braking performance on your 1999-2004 Porsche 911 (996), this Brembo GT Big Brake Kit for the rear is a serious consideration. This kit is designed to replace your factory rear brake components with a much larger and more capable setup, giving you improved stopping power and heat management for spirited driving or track use. It features substantial 4-piston calipers and a two-piece rotor design that offers better thermal stability.

The heart of this kit lies in its robust construction and thoughtful engineering. The calipers are cast aluminum, which keeps weight down while providing a solid foundation for the pistons. These calipers work with large 345x28mm two-piece rotors. The two-piece design, where the rotor hat is separate from the friction ring, helps to reduce heat transfer to the hub and allows for more expansion and contraction without warping. The rotors themselves are slotted with Brembo's Type III pattern, which is known for its effectiveness in clearing out brake dust and gas buildup, ensuring consistent pad contact and improved cooling under heavy braking. This kit comes with everything needed to install the calipers and rotors, including mounting hardware and brake lines specifically designed for this application.

When installing a big brake kit like this, it's important to remember that it's a significant upgrade. You'll want to ensure your brake fluid is fresh and of a high enough rating (like DOT 4 or higher) to handle the increased temperatures. It's also a good idea to bed in the new pads and rotors properly according to Brembo's instructions to get the best performance and longevity out of the system. This kit is a substantial investment in your vehicle's performance and safety, offering a noticeable improvement in braking feel and fade resistance.
