Yes indeed Paul, and if I remember rightly there was a few near missess with LMP 900 machines and the slower cup class cars. Although that probably has something to do with the weather at least in part. Not to mention the closing speeds between LMP 900 cars and the Cup class machinery. With FIA GT's though it could be differnt as the closing speeds woudnt be as big as the GT1 class machinery is still a little way off the LMP 1 class.
One problem I do see with the NGT British GT runners running alongside the FIA GT's is that the maximum entry number for FIA GT is 36 cars, plus 2 additional entries from the host nation. Now, assuming the FIA GT championship gets say 28-34 cars on average next year where are u going to put the 10-15 NGT cars from the British GT championship?
