Porsche 911 GT3 Cup/GT3R/GT3RS

THE GT car of many decades.  Over 30 should start at Daytona this year and will make up the bulk of the GT field until the Prep 2 rules really kick into gear.  It will probably take a win from the RX-8 or GTO to drive customers away from the venerable, and numerically superior Porsche.
