Oswaldo Negri and Burt Frisselle brought home third-place honours in the #6 Michael Shank Racing Doran, in spite of it being the duo's first race together.
Magnussen and Papis met with Grand American officials following the race and were informed that penalties will be assessed following review of video footage of the race early next week.
After a disappointing finish at the Rolex 24 At Daytona, Performance Technology Group swept the top two spots in the GT class. Sportscar veterans Boris Said and Bill Auberlen showed the liking for Homestead by taking top honours in the #21 BMW M3, while team-mates Joey Hand and Justin Marks finished second in the #22 entry. The win, coupled with the #21's fastest qualifying time, earned PTG a $5000 bonus cheque in the Acxiom Grand Touring Challenge.
Behind the two M3s, The Racer's Group #67 Porsche claimed third in the hands of team boss Kevin Buckler and Grand-Am debutante Liz Halliday.
If the Howard-Boss team's comeback was inspiring, it was matched all the way by that of the winners in the new SGS class.
Craig Stanton and David Murry overtook the entire SGS field to take victory in the AASCO Motorsports Porsche GT3 Cup, having been forced to start at the back of the grid after failing a post-qualifying technical inspection.

TPC Racing rounded out the SGS podium with Randy Pobst and Michael Levitas taking second in the team's Porsche and Marc Bunting and Andy Lally finishing third in the #38 example.
