Kiwi Supercars star Shane van Gisbergen joins Martin Devlin on It's Only Sport ahead of his trip to the USA, where he'll make his much anticipated NASCAR debut. Van Gisbergen will take part in the Cup Series' Chicago Street Course event on the first weekend of July. The three-time Supercars champion and two-time Bathurst 1000 winner talks to Martin all about how the opportunity to drive in NASCAR came about, how much preparation he'll get ahead of the race, the challenges of driving a NASCAR vehicle as opposed to a Supercar, and more.
