The race replaces the previously announced participation by the series in next weekend’s Spring Vintage Classic and is now the first of two Sebring stops on the 2015 Stuttgart Cup/Mission Foods GT3 calendar. The season will once again conclude on the legendary Florida circuit at the Sebring Historics this December.In addition to the new Sebring race date, the return to the Savannah Speed Classic, October 22 – 24, fills the only open date on the 2015 Stuttgart Cup/Mission Foods GT3 calendar.

We are also looking forward to returning to the HSR Savannah Speed Classic that has grown into a premier event the last few seasons. These great events place the final touches on a fantastic 2015 racing schedule.”The Sebring event entry form is available by clicking here while the provisional race schedule can be downloaded by clicking here.The 2015 season began with last weekend’s Palm Beach Grand Prix, February 12 – 14, at Palm Beach International Raceway (PBIR). The new Sebring date now gives Stuttgart Cup/Mission Foods GT3 competitors more than a month to prepare for the 12-hour weekend, which was another key factor in the date change.Following Sebring, The Stuttgart Cup and Mission Foods GT3 series debut at Homestead-Miami Speedway, April 9 – 12, at the Miami Historics.The Stuttgart Cup/Mission Foods GT3 series then head North to Road America for the Spring Vintage Festival, May 14 – 17, and the Mid-Ohio Sports Car Course Mid-Ohio Vintage Grand Prix, June 25 – 28. An autumn return to Road Atlanta for the second-straight year, September 14 – 17, at the Atlanta Fall Historics will be first of what is now back-to-back Georgia races with the Savannah race addition the following month. The 2015 calendar concludes with what has become the traditional season-ending Daytona Historic Races, November 12 – 15, and the Sebring Historics finale, December 3 - 6.Open to all Porsche Caymans, Boxsters and 996, 997 and GT3 Cup cars, 2015 marks the second full season that The Stuttgart Cup™ and Mission Foods GT3 Cup series will race together. Showcasing Porsche Caymans and Boxsters, The Stuttgart Cup is beginning its fourth year of racing and third full-season of competition this year. Partnering with Mission Foods GT3, which has been a fixture on classic and historic race weekends for the last several seasons, was an ideal collaboration that attracted strong competitor interest and the support of Pirelli Tire in 2014.
