First announced as the Team GBR driver halfway into the 2008/2009 series at Taupo, New Zealand, Clarke had little time to adapt to the new car, team and track. He went on to build experience through that weekend and then at the Portimão, Portugal, races. The next race for Clarke was Brands Hatch, UK, in front of his home fans. Despite Qualifying technical issues, Clarke put on an impressive performance to drive back from 14th place in the feature to 7th scoring fastest race laps in the process.
