YouTube - State Championship Finals - 2007 - Race 02 In-car
1st gen RX7, reverse grid, 360 odd rwhp, 13bt bridge port. reverse grid 25+ cars!!!! Evos, WRX's Skylines, Type R's all race in these two classes. Both classes are separated into under and over 2 liter which is whay there's such a speed difference with some cars
Pinched from another forum:
"The grid is combined WA StreetCar class and the national Improved Production category. All the turbo RX7s (Gen1 and Gen3) you see are Street Cars. A couple of non-turbo RX7s are IP. Most (a couple of exceptions) smaller capacity cars are IP. All the 4WDs are IP and you may even see a VL turbo - also IP. The turbo Nissans are all StreetCars"
The reason there are so many Mazdas is becasue they represent excellent value from money compared to just about everything else. Performance/reliability per $ spent is much better. Even the FD's.
Enjoy!
