August 20, 2017 iRacing added a new race to the 2017 endurance schedule, 500 km of Road America. While the track was well known to the team the Audi 90 and Nissan GTP were not. With a short window for race preparation following the Watkins Glen race Skid Mark Motorsports prepared 1 car for the event. Bart Workman and Scott Johnson would enter their Nissan GTP as a two driver entry in the first race. While cars fell by the wayside as drivers crashed in the early laps of the 2.5 hour event, the Skid Mark Motorsports team drove through it all. With a 43 car field the team started 12th and finish 13th while having to make a short stop for some minor body damage.
The following day Scott Johnson made a solo entry in the teams Nissan. Due to missing qualifying he made the grid in 32nd position in a 46 car field. After his 2.5 hour endurance run he was able to reach 11th position by the checkered flag.
It was a good race weekend for the small team that was able to make 2 decent finishes in the vintage turbo race car. The team is finally able to take a little breather as they prepare their cars for the 10 hour Petit LeMans race at Road Atlanta at the end of September.
