Re: 20 inch wheels?
First, the rubber on the road is not linear as you go to wider tire, i.e. a tire twice as wide doesn't put even half as much more rubber on the road. Second, grip is based on area times down force (weight of car). So just as tire width doesn't increase area as much as you might think, more area also means less down force per inch of that area. Third, you can put wider than 225s on these cars (the factory does it!). Fourth, the optimum amount of rubber depends on the weight of a car as much as the power. This is a 33-34xx lb car not some tub o' lard Camaro. Fifth, get some performance tires and you will be fine.
