When it comes to racing Porsches in North America, the name Brumos is the stuff of legend. The Jacksonville, Florida dealership has been building winning Porsche race cars for the better part of five decades, and it’s now working with Porsche Motorsport North America to offer a special edition of the 2012 911 GT3 Cup racer.

Built to compete in a variety of series including Rolex Grand-Am, SCCA, Porsche Club of America and Porsche Owners Club events, the 911 GT3 Cup is a competent race car right out of the box. Now, to celebrate its 2011 Rolex Grand-Am Championship, Brumos will build the final five 2012 GT3 Cup cars to its own proven specifications.

That means that each copy bears the white, red and blue Brumos livery, and comes packing a 4.0-liter flat-six engine tuned to Grand-Am specifications. Output is rated at “more than” 450 horsepower, and each car comes equipped with a rev-matching system for expert downshifts, regardless of driver experience.

The Brumos 911 GT3 Cup Cars get a Motec data acquisition system, too, to keep tabs on lap times and advise whether or not you need to pick up the pace. Each car wears a “911 GT3 Cup 4.0” badge on the rear deck, reminding other GT3 Cup drivers that you’ll be passing them on the straights.

Since this isn’t an ordinary race car, delivery of the five available copies will be pretty extraordinary, too. Buyers will get the keys (figuratively speaking) at a dinner event that includes guests Hurley Haywood, Leh Keen and Andrew Davis, and also get a tour of the private Brumos Collection.

The price for all this heritage and performance is $265,259, excluding taxes. You’ll need a tow rig to pick up your car, too, although we’re pretty sure Brumos would be happy to arrange delivery if needed.
