Product Description

19-inch wheels or custom 18-inch wheels are required for clearance of the larger rotors and calipers.
OEM 18-inch Porsche wheels cannot be used with these brakes.

Brembo's rear GT Brake Upgrade offers superior performance and lower weight than OEM brakes. It is designed to work together with the Brembo GT Front kit.

Replace the factory 350mm steel rotors (or in some cases 380mm PCCB Ceramic) with 380mm x 28mm 2-piece floating rotors and larger monoblock 4-piston calipers in the rear. 


  • Single piece lightweight aluminum calipers
  • Two-piece 380mmx28mm steel rotors with aluminum hats
  • High performance brake pads
  • Steel braided brake lines

The Brembo kit also reduces the unsprung mass on cars with steel brakes by approximately 15 pounds from the rear of the car.

For certain models equipped with PCCB brakes (such as the 2007-09 997TT), this upgrade offers cheaper replacement costs for track use.

This kit is also available with slotted rotors (as shown here) for track oriented cars at no additional cost. Calipers are available in silver, black, red or yellow.

Available as a complete set or individually for front or rear axles. Although we recommend that this front kit be used in conjunction with a Brembo GT front system also.

Fully compatible with ABS and traction control systems
Brembo engineers design each brake upgrade specifically for your vehicle and driving conditions. Optimum brake balance is achieved by combining Brembo's thorough knowledge of OEM braking systems and use of an unlimited range of caliper, piston, and disc combinations. Brembo brake upgrades are easy to install and designed to work seamlessly with your vehicle’s stock master cylinder, ABS, and traction control system.

Brembo calipers are equipped with unique pad retaining features and sequential piston bores in order to provide even pad wear and optimum performance. 

Brembo calipers incorporate a twin seal design that restricts dirt and debris from entering the caliper body and contaminating the brake fluid. This extends caliper life by protecting the pistons and internal pressure seals and prevents the need for maintenance. Brembo calipers undergo a strict homologation process which exceeds the requirements set by OEM manufacturers.

All Brembo caliper mounting brackets are designed vehicle and system specific. They are precision milled from superior quality billet materials to ensure a precise fit and meet the strength requirements of high performance driving conditions. Brembo brackets are also further analyzed and tested to ensure fatigue life.

Brembo caliper mounting brackets are also anodized to provide an attractive finish. Each Brembo system includes all necessary hardware for ease of installation (please read instructions prior to installation).

Cross Drilled Rotors:

  • Cross drilled discs run at slightly lower temperatures due to added air flow through the surface of the disc where heat is generated.
  • They are also highly effective in wet conditions and shedding debris from the disc to ensure a clean braking surface.
  • Improve pad “bite”, improve wet weather performance, continuously refresh the brake pad

Slotted Discs:

  • Slotted discs are recommended when using race pad materials or compounds. the vehicle is submitted to extreme braking duties such as towing or hauling heavy loads.
  • Improve pad “bite”, improve wet weather performance, continuously refresh the brake pad
