To be honest we can't make perfect balance. The major difference between cars is how difficult to drive they are. Each car will perform differently depending on race type. We can make each car harder/easier to drive but that's about everything. Skill sometimes plays a big role in this, as some cars are difficult to drive but that's being hidden by some people who are very experienced racers.
