Just rememeber something else - the cars themselves.
On the first green flag lap prior to the feature Muller was weaving heavily to get heat into his tyres and I was amazed at just how little grip the car has. Several times I thought he was going to lose the backend.
Coming into Paddock during the sprint Muller and Plato were locking up under brakes on nearly every lap.
Again coming through Paddock the cars were lifting the inside rear wheel (Bennett more than anyone else) and around Graham Hill Soper was regularly on 2 wheels.
Just in case anyone wasn't convinced these are definate NOT SuperTourers
