THE SHANNONS NATIONALS presented by Hi-Tec Oils has revealed the final breakdown of events and categories for the 2012 season.

The nine rounds across four states feature an average of six categories at each round, representing the diversity of the Australian Motorsport landscape with everything from Touring Cars to nimble open wheelers and everything in between.

It is the most diverse Shannons Nationals calendar yet announced in the series six-year history.

 The class structure for the Australian GT Championship has been revised and expanded to cater for a wider variety of exotic sports cars for the 2012 season. The series will now feature four classes, the outright GT Championship class headlining the latest 2011 spec cars complying to FIA GT3 regulations, such as the Ferrari 458 Italia, Lamborghini Gallardo GT3 - LP600, Ford GT- 40 GT3, Mercedes – Benz SLS AMG GT3, and Audi R8.

The GT Trophy class has been added to allow older spec GT3 cars to remain competitive. Cars such as the Ferrari 430, Lamborghini LP520, Porsche GT3 997 Cup S and Dodge Viper Competition Coupe Series 1 are now eligible for class honors, as well as mixing it up with outright contenders.
