G'day mate!
Well, there has been a bit of discussion on the classes etc - as our skylines werent (r33) werent locally produced.
I have entered in SVD as so have the other guys here - I dont know why Steve hasnt as I wasnt sure about his supra.
When you call them to see if there are spots left, have a discussion with them about the groups, but worst case just enter SVD and may be able to change on the day?
The hillclimb - Im hoping you have seen the bathurst 1000?
if you see mountain straight - the climb up the hill....there is basically walls everywhere with little to no room for error!
I personally wouldnt do it for my 2nd driving event, even last year when I did it on street tyres, I got a bit taily and my heart went crazy...haha
if you do it at your own pace and know your limits, go for it!
