yannis,
will have to look at that duing my lunch break tomorrow (my speed is profiled at home at present...slow).
Bathurst is only 65 km away, and it's a great drive (public road). I remember when Gricey did the first average 100MPH lap, an utterly incredible feat.
I've got mates who hillclimb there. They do it backwards up from the straights. It's scarey to watch guys flat bickie half a hand width from a concrete wall.
