Tell me again why they can't compile a banned car list based on power to weight? I seems that would make much more sense than this system. It may be a little more difficult to compile a list of cars and their power to weight ratios initially, but surely it would be alot easier to police in the long run?? As I mentioned earlier, a Holden HK Brougham with a 253 in it is going to have a vastly different power to weight ratio compared to an Integra Type R. As SW20-GT mentioned, you can still do a hell of alota damage in the family wagon.
Dimwits who want to speed and act anti-socially in their cars are still going to do so. They will be just doing it in cars with crap brakes.
Thats my opinion anyway. (Be it right or wrong!)
