Tip: Always start on wet tires when the forecast calls for rain (even if it isn't due to hit for a lap or two). Although fitting dry-weather tires on a wet track will put you at a serious disadvantage, the reverse isn't true at all. Not only can you maintain a fast pace on a dry surface with wet tires, but you will also eliminate the need to pit should it start raining. This will gain you buckets of time over the AI drivers who automatically pit once the track turns wet.
Tip: Some of the A-class (and even B-class) cars may boast impressive top speeds, but this will offer you no competitive advantage on any of the game's ten circuits. If you're determined to compete in the A-class, you should go for one of the slower cars that offer superior roadholding (such as the Shelby Cobra look-alike). However, the opposite holds true in the beginner C-class, where you'll want to get your hands on the speedy Ginetta G33 as soon as you can afford it.
