The world really has gone mad hasn't it?
Unfortunately someone or some department was paid alot of money and spent alot of time to dream up the "rules". I'd say 60-80% of cars that over 10 years old probably don't comply with the above.
I think I'll just do what everyone does and put the bigger rims on anyway! Of course the Wildfires can always go back if need be.

Thanks for the input guys - I'll post some pics of what I end up doing
