I agree its bloody good fun me and a couple of the Canberra guys were there a fortnight ago. It was mine and one other guys first time. Our day was a little more nerve racking for me personally as I was the slowest car there and I did a 1.18.76 and 1.19.00. There were about 8 evo's, couple of rotors, WRX, MR2, clubsport and 3 skylines.
all in all great day just make sure you take it easy for the first half of the day as you will slowly build your confidence to go faster
on that note I only managed 175km's down the straight or there abouts.
