Brembo 03-16 Phantom Sedan/Coupe Rear GTR BBK 4 Piston Billet 380x28 2pc Rotor Drilled- Nickel

If you're looking to significantly upgrade the stopping power on your 2003-2016 Sedan or Coupe, this Brembo Rear GTR Big Brake Kit is a serious consideration. This kit is designed to replace your factory rear braking components with a much more robust setup, featuring large 4-piston calipers and substantial 380x28mm two-piece rotors. The goal here is to provide a more consistent and powerful braking feel, especially under demanding conditions where heat can become a factor.

The calipers in this kit are crafted from billet aluminum, which is both strong and lightweight, and they house four pistons to distribute clamping force evenly across the braking surface. This helps to ensure more effective pad contact and better heat dissipation compared to smaller, single-piston calipers. The rotors are a two-piece design, meaning the aluminum hat is separate from the iron braking surface. This design helps to reduce weight and manage heat more effectively, as the hat can expand and contract independently of the rotor ring. These specific rotors are drilled, which helps to vent gases and moisture away from the pad surface, maintaining better grip, and they measure a substantial 380mm in diameter and 28mm thick, offering a large surface area for braking.

This kit includes everything you need to perform the rear brake upgrade, including the calipers, rotors, and necessary mounting hardware. It's a comprehensive package for those who want to ensure their vehicle can stop as well as it accelerates. Remember to consult the manufacturer's installation guide for specific details on fitting this kit to your vehicle, as it involves replacing major braking components.
