A change will be in order this weekend as he leaves the WSK Super Master Series to go and race in the IAME Euro Series at Mariembourg this weekend. Switching the OK for the X30 engine, Callum will be returning to the series he became Vice champion of last year and will continue to represent the Tony Kart brand with Strawberry Racing. After a clean sweep of victories at the season opener last year Callum will be aiming for nothing short of the same this year.
