It does come with a price, longer wheel base and track width hurt on really tight tracks. The problem is that a wider or longer car can't "cut the corners" as much as a narrow car. This is why a Miata can do so well on a tight autocross track as compared to more powerful cars that would handily beat it on a road course. On a very tight track the Miata is simply able to run a straighter line through the corners. However, on a larger circuit with faster turns the Miata's short wheelbase and narrow track become a liability. Some people might assume the Miata losses out to more powerful cars simply due to a lack of power. However, if the more powerful car's CG is lower with respect to it's wheel base then it may also perform better in turns as well as through transitions.

That makes good sense, I know it's a horrible way to learn, but I remember in Gran Turismo 4 I was driving a real classic car (Honda S800 racer maybe?) and I was putting out pretty respectable lap times. It's a really small car, so it definitely makes sense now.
