(ok post in the order you enter the race, each lap is 4 post 3 lap race. the order you enter is each race is the starting postion. if your geared for acceleration you get off the line faster but overall top speed is lower the opposite holds true for top speed gearing. heavier vehicles are harder to control but have more powerful engines normally so are faster than the lighter ones as far as a is concerned straight line, the lighter vehciles are more nimble so there better in the cornors)
