I've never heard of SVD (but I'm relatively new to this) - When I was racing the GTR, I was in SV and was under the impression that if I did too many mods, I would go into another class, I suspected Super Sedan, but never did any mods to find out.
If you were doing local club events, only 4wd cars go in SV i.e. EVO's. WRX's and GTR's and non 4wd like my GTST goes into Type 2 over 3001 (x1.7 for turbo).
I'll have to check what class you would be in for a state level, unless Neil knows???
Come down and warm up on our little track, bring Neil with you cos he has to look at the track before the state round next year and if you want to take this further, let the speed weekend be a warm up for Round 1 & 2 of the state round which is also at Bathurst on 7-8 March (a day each doing Esses and Mountain Straight).
You can register for the series on Neils link and nominate a number - I should be able to give you some hints on available numbers if you need help.
Last weekend at Bathurst was so much fun that I didn't want it to end.
