Brembo 01-04 996 C4S Rear GTS BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type1-Black HA

If you're looking to significantly upgrade the braking performance on your 2001-2004 Porsche 996 C4S, this Brembo GTS 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 robust setup, featuring 4-piston calipers and substantial 380x28mm two-piece rotors. The primary goal of a big brake kit like this is to improve stopping power, heat management, and overall pedal feel, especially during demanding driving conditions or track use.

This Brembo kit utilizes a cast aluminum 4-piston caliper, known for its strength and ability to house larger brake pads for increased surface area. The two-piece rotor design, with its 380mm diameter and 28mm thickness, offers a larger thermal mass to absorb and dissipate heat more effectively than stock rotors. The rotors are slotted, which helps to sweep away dust and gas that can build up between the pad and rotor surface, maintaining consistent braking performance. The Type 1 black finish on the calipers adds a clean, performance-oriented look to your rear wheels.

Included in this kit are the necessary components to perform the rear brake upgrade. You'll receive the Brembo 4-piston calipers, the 380x28mm two-piece slotted rotors, and likely the associated hardware for installation. It's always a good idea to consult the manufacturer's installation guide for specific details on mounting and any additional items you might need, such as specific brake fluid or potentially new brake lines if recommended for optimal performance with this upgraded system.
