"GT3 cars are coming to the United SportsCar Championship in the GTD class next year. Here&amp;#039;s why you should start getting excited.  Over the past few seasons, the popularity of FIA GT3 racing has exploded across the world. Countless series have cropped up in Europe, Asia, the Middle East, and South America, and thanks to new rules put in place by the United SportsCar Championship, GT3 spec cars are now eligible to race here in the United States next season in the GTD class.  Several manufacturers have gotten in on the action by selling factory built cars to private teams. In Germany alone, it&amp;#039;s become blood feud, where Audi, BMW, Mercedes-Benz, and Porsche act as puppet masters over numerous independent racing outfits, and battle for bragging rights on tracks across the world.  GT3 regulations were drawn up so the cars would be cheap to operate, easy to drive, and hard to break. Though regulations can vary slightly between series, parts can be easily switched out to accommodate different sets of rules. The USCC, for example, will require GT3 cars entered in the GTD class to use a spec rear wing. In addition, most cars come equipped with built in air restrictors that can be easily adjusted for further balancing. This adjustability means that it&amp;#039;s not uncommon to see teams float between multiple series in a single season.  &amp;quot;There actually aren&amp;#039;t too many differences,&amp;quot; said Flying Lizard Team Manager Eric Ingraham, when discussing the difference between GTD and GTLM, &amp;quot;with telemetry and a relatively complex car, you need the same number of people to run the car in terms of data specialists and mechanics. The GT3-derived GTD spec car is obviously more street car based but is technically advanced enough that a similar sized crew is needed.&amp;quot;  Flying Lizard will be making the switch to an Audi R8 LMS this season after several years of running Porsches in both the ALMS GTE and GTC classes, &amp;quot;It&amp;#039;s certainly cheaper than a GTLM car as the frequency of parts changes is lower while the unit parts cost is also cheaper.&amp;quot;  Take a look at the GT3 racers that are already in competition across the world, and then get excited that many of them will be doing battle on our shores starting next month at the 2014 24 Hours of Daytona. Between the 27 cars entered in GTD and 12 cars entered in GTLM, GT racing is about to get very exciting. "^^<http://www.w3.org/2001/XMLSchema#string>
