Jim Clark’s first race with the Jaguar TKF9 was on an airfield circuit at Full Sutton in Yorkshire earning him an early place in the record books. He was the first sports car driver to lap a British circuit at over 100mph. The contrast with bumpy Charterhall was profound. Full Sutton had a long 3.2 mile lap and was in perfect condition. The American Air Force had just spent a quarter of a million pounds - a lot of money in 1958 - resurfacing it.
