2007 Porsche 911 GMG 997TT WC-GT2 GT2 Cup Car Description

Thank you for taking a look at another unique piece of fiveninedesign inventory. True to our nature, we are very proud to be able to offer this one of a kind, once in a lifetime, 2007 Porsche 997TT dubbed the “WC-GT2”. This is undoubtedly one of, if not the most radical Porsche’s on the planet, and definitely the most complete street/track car ever created. It will be hard to explain in a small description about the car, but chances are if you are looking at this ad, and you are serious about the car, you know exactly what it is. We will do our best to tell you in words about the car, but it does it absolutely no justice. For those that don’t understand this car, here is a simple way to put it. The purchaser of this vehicle will sign a legal document assuming all responsibilities that come with a vehicle of this nature, as we will not be responsible for your life should you go try and be a track hero. This car is NOT for the feint of heart, not for the amateur, and definitely not for someone who thinks they are capable of taming such a beast. This car will DEMAND that you learn how to respect it, and your learning curve will be a long, slow process. Once you master a car of this caliber, you will truly understand what it feels like to be able to wheel a true, non forgiving, supercar.


GMG Racing is a company based out of Orange County, CA. They are a premier Porsche shop with ultimate specialty in Professional Porsche Racing, and high performance Porsche products. They are, basically, the best of the best when it comes to Porsche, and Porsche Racing. They were commissioned by a very powerful person, to build the ULTIMATE 911. No stone unturned, no corners cut, the most detailed 911 build in the world, utilizing the best parts available. If a part good enough wasn’t available, then it was made especially for this 997. This masterpiece was named “The Green Monster”. Starting life as a 2007 Porsche 997 Turbo, and three years later, over $340,000 later, (in JUST build and products), the car was completed and the most extreme “World Challenge” car that GMG has built. Most of the WC cars are GT3’s and GT3RS’. This is the one and only forced induction variant, and by far, the most extreme. Upon completion, the car was stored, and unused, and to this day has never been tracked. Having a one off, 4.0L Twin Turbo Motor built by GMG, utilizing parts from all sorts of Porsche race cars, this car is truly next level. The full build was done on a rotisserie, the car was painted inside AND out, and everything was done with white glove service. We were just fortunate enough to come across the car in good standing condition, and we did what we do best, we made it BETTER. With a FULL engine rebuild being complete less than 100 miles ago, this car is ready to pack miles as a wicked street car, or ready to hit track events and set fastest time of the day at every track nation wide. Here is a list of modifications done to the car, which is not close to a full list, but as much as we could come up with.

This is not anywhere NEAR everything that is done on this machine. This is a glimpse into the machine you are looking at. Everything works. Everything was done with the driver in mind. Everything is one step beyond anyone else’s 911. Pulse Racing Services, with the help of everyone involved in the project when it was new, recently did a full tear down and rebuild on the motor. Did it need it? No. Is it nice to know that this is a fresh rebuilt race motor? Yes. In it’s current configuration, the car is running on Wastegate boost, (~15lbs), and put 671 RWHP to the ground. Yes, the SLOWEST configuration of this machine makes over 670 Wheel Horsepower. This car, capable of 23-25 Lbs. of Boost on MS109 Race Gas, should be very capable of putting down over 900 Horsepower to the Rear Wheels. Combine this with a car that should weigh around 2,800 lbs, and is rear wheel drive, and you quickly understand that this is a modern day 935 Porsche. A modern day, high horsepower, visceral, face ripping machine. The original MSRP of this $137,895.00, and the upgrades are over $350,000.00. Yes, this is a HALF of a MILLION Dollar CUP CAR, that you can drive on the street. The build only has about 7,300 miles on it, and is ready to go. Test drives are NOT prohibited. Real buyers are more than welcome to come look at the car, ride in it, get a full PPI from the Porsche dealer (who LOVE this car), and pay for it to take it for a drive. It is too fast, too dangerous, and too much risk to let anyone drive without owning it. Many times, you see an ad like this and notate most of it to “smoke and mirrors”. I think it is safe to say that this build is the exact opposite. This is the real deal. This is the BADDEST 911 on the planet. End of story.
