Here is a one off car from the Grand Am race at the 2013 Laguna Seca. Well I assume it was just this race as it wasn't at Road America and SSF is a San Fran based parts company that also sponsored USTCC cars that were at Sears Point that weekend also.
Couldn't find a lot on the team or sponsors so some I pulled from pictures and recreated. Still it was a pretty cool looking skin.
