Brembo 99-04 996 Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Slotted TY3L - Black HA

This Brembo rear big brake kit is designed for the 1999-2004 Porsche 911 (996) model. What you get in this kit are the essential components to significantly upgrade your rear braking system. It includes a pair of robust 4-piston calipers, which offer more clamping force than stock, and a set of 345x28mm two-piece rotors. These rotors are slotted, meaning they have grooves machined into the braking surface. The two-piece design allows for better heat management and easier rotor replacement down the line.

The calipers in this kit are cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the pistons. The rotors are a two-piece construction, featuring a cast iron friction ring bolted to an aluminum hat. This design helps dissipate heat more effectively than a single-piece rotor, reducing the risk of brake fade during spirited driving or track use. The slotted design on the rotor surface helps to sweep away dust and gas that can build up between the pad and rotor, maintaining consistent braking performance. This kit is a substantial upgrade for the 996, aiming to improve stopping power and heat resistance.

When installing a big brake kit like this, it's important to ensure you have the correct tools and follow the manufacturer's installation instructions carefully. Because this is a significant brake system upgrade, it's often recommended to pair it with a high-performance brake fluid and potentially upgraded brake lines to take full advantage of the new hardware. This kit is a serious investment in your vehicle's performance and safety, offering a notable improvement over the factory braking components.
