Unfortunately, that was the last race of the season, and Procar has shut up shop, so we'll have to see what happens next year.
Basically, there were 4 catagories:
Nations Cup: Lamborhini Diablo, Porsche GT2/GT3, Ferrari 360's, NSX etc.
GT Performance: WRX's, Evo's, M3's, R32 Golfs etc.
GT Production: Basically production cars. Corollas, Beetles, Copen, lots of cars.
V8 Brutes: Ford and Holden V8 Utes (last pic)
Good racing, mix of privateers and factory backed teams. Lots of varying driver ability and car speed.
