That's it. I know a number of cars have had big accidents out on the back track. Years ago (prob '99ish) I saw a very high powered Datto 120y hit the tree, going clockwise towards the 2nd hill, coming out of the lh sweeper. Destroyed it. Earlier that day his daughter lost it into the first turn, went through the fence into the paddock where the houses are now. That was a sprintrun by the Shep car club. I was running in my red mazda (in my avatar)
Thanks to everyone pointing me in the direction of tyres. Kumho has no 225-45-17s in stock in nsw or vic. Luckily Essendon tyre power had a very good set of second hand 225s which suit me perfect! 225s front, 255s rear. Thanks again guys! Can't wait for Saturday!
