He finished 6th at Portland International Raceway and 7th at Burke Lakefront Airport, where he was battling for 2nd with Mario Domínguez when they collided on the penultimate lap.

Following on from Denver, Clarke continued to run at the front and narrowly missed out on another podium finish at the next race in Montreal, Quebec, coming home in 4th place.

Clarke had a troubled season finishing 13th in the overall standings and missing one race, at Zolder having been ejected from the event for causing a multi-car crash in practice.

Despite qualifying technical issues, Clarke put on an impressive performance to drive back from 14th place in the feature to 7th scoring the fastest race laps in the process.

In 2011, Clarke competed in a NASCAR Nationwide Series race at Watkins Glen International, finishing 39th following an engine failure.
