Brembo 03-07 Cayenne/S/Turbo Rr GTR BBK 4Pis Billet 380x28 2pc Rotor Drilled-Nickel

This Brembo Rear GTR Big Brake Kit gives you a substantial upgrade for your 2003-2007 Porsche Cayenne, Cayenne S, or Cayenne Turbo. You're getting a complete rear braking system designed to handle more demanding use. This kit includes a pair of Brembo's 4-piston billet aluminum calipers, two 380x28mm two-piece rotors that are drilled and nickel-plated, and all the necessary hardware to get them installed. It’s a well-built package aimed at significantly improving your vehicle's stopping power and heat management.

The calipers are forged from billet aluminum, which is strong and lightweight, helping to reduce unsprung weight. They feature a 4-piston design, meaning more pad surface area is in contact with the rotor, which translates to better braking force. The two-piece rotors are a notable upgrade; the floating design allows the rotor ring to expand and contract independently of the hat, reducing the risk of rotor warping under extreme heat. The 380mm diameter and 28mm thickness provide a large thermal mass to absorb and dissipate heat effectively. The drilled pattern on the rotors helps to vent gases and heat away from the braking surface, maintaining consistent performance even during hard braking. The nickel plating on the rotors offers corrosion resistance, keeping them looking good and functioning well.

Installing a big brake kit like this is a significant undertaking, and it's recommended to have a qualified mechanic perform the work. You'll want to ensure you have the correct tools and follow the manufacturer's installation instructions precisely. This kit is designed to be a direct fit for the specified Cayenne models, but it's always a good idea to double-check compatibility with your specific vehicle's wheel size to ensure clearance. The result is a much more responsive and powerful braking system, ideal for drivers who push their vehicles hard or tow heavy loads.
