Stevenson Motorsports has been competing regularly in GRAND-AM since 2003. The team had limited success from their first race and podium at Watkins Glen with John Stevenson behind the wheel running a Porsche GT3 RS. From 2005-2007, Stevenson campaigned Corvettes built by Riggins and Crawford, but it wasn't until 2008 when the team's second podium and first win came at Mexico City with their three-race old Pratt & Miller Pontiac GXP.R. It would be the first of 14 podiums over the next two years including five more wins at VIR (2), Montreal (2) and Barber.
