If anyone is interested.

I watched it last night was pretty interesting. I think they changed the series a little so its easier to watch as the first airing of it they looked at loads of different projects in one episode now it seems to be focused on one car.

I really don't fancy sitting with my nuts 3" above a propshaft spinning at 8000rpm...

Oh - and no roll bar to speak of - there was part of the frame, but that was an inch or so lower than the top of the driver's helmet...
