The single-seat, aluminum-bodied racer with Maserati style lines quickly propelled McKay to on track success finishing as the highest placed MG in the 1952 Australian Grand Prix at Bathurst along with solid wins and placings at events in Gnoo Blas, Nowra and Mount Druitt across the season of 1953.

Then in 1960 McKay achieved the most memorable victory in his career, winning the inaugural Australian Touring Car Championship at the Gnoo Blas circuit in Orange driving a Jaguar Mark 1.

McKay had the right to protest and have his name added to the list of Australian Grand Prix winners when it was found later that day that he had not committed a jump start after all.

Jim Palmer and Phil West finished 2nd outright behind the winning Monaro of Bruce McPhee and Barry Mulholland.

Brian Muir and 1964 winner George Reynolds finished 5th while the Paul Hawkins / Bill Brown car was disqualified.
