Dave's car has a roll bar in it - that's so neatly installed you really have to look close to see it. I looked at his car when he was assembling it - the attention to detail is incredible - small things add up in weight reduction - and the go-fast secrets are well hidden. Flat out its an impressive car and driving that thing has to be a handful - but Dave makes it look easy and I am sure he is already planning for the 9.80's.
