The 2017 Continental Tire SportsCar Challenge (CTSCC) championship came down to two Porsche Cayman-based entries; the No. 28 RS1 Cayman GT4 Clubsport MR and the No. 12 Bodymotion GT4 Clubsport. The two iterations of the Porsche sports car, which shares 80 percent of its parts with the road-going Cayman GT4, split two wins in the GA class which balances grandfathered IMSA GS class cars (Cayman GT4 Clubsport) and the GT4-specification car (the GT4 Clubsport MR). With a total of ten race podiums over the season, Porsche was awarded the Manufacturer’s Championship over Ford by seven points.
Bodymotion was the veteran team with the German model having won three races in 2016. The New Jersey-based program with drivers Cameron Cassels (Canada) and Trent Hindman (Wayside, New Jersey) would come 13 points short of the GS class newcomers, RS1, in the team chase when the checkered flag flew at Road Atlanta. The drivers of the No. 28, Dillon Machavern (Burlington, Vermont) and Dylan Murcott (Ancram, New York), used their five podium finishes – seven top-five results total in ten races – to score their first CTSCC GS title with Porsche. The No. 28 took its sole victory of the year in the two-hour races at VIRginia International Raceway (VIR).
Porsche Cayman GT4 Clubsport models swept the Top-Four at the season opening race, a four-hour endurance event at Daytona International Speedway, and took the top-three positions in the final GS class standings for the year with the No. 33 CJ Wilson Racing entry, which scored three podium results but no victories in 2017. Drivers Marc Miller (Grand Rapids, Michigan) and Till Bechtolsheimer (New York, New York) had a season-high finish of second-place at Daytona in January in the No. 33.
It was the second season for Porsche Motorsport to officially participate in the road car-based race series and was the first championship for Porsche Motorsport in the IMSA-sanctioned championship. The Porsche Cayman GT4 Clubsport finished second and third in the 2016 championship.
