I don't think it's that stegger. The cars have been ultra reliable in the UK so that points to the problem been the conditions in Italy. It can't be grip, because we have high and low grip here. I don't think its dust, we have that here to. Heat is a possibility, but its hot in the USA and they've never had a problem. Track style/layout, again no problems in the USA. That's why its a bit of a mystery
