Have you ever wondered why fuel burn-off typically does not change the handling of a race car, at least not a great deal? I have been asked many times when helping teams setup their cars, what will the car do when the fuel burns off? My standard answer is, I have never seen much change. And that remains true, at least when we have achieved a more balanced setup. I have setup cars that have run 200 lap races on one load of fuel and not seen any appreciable change in handling. The car burned almost twenty gallons of race fuel, or 120 pounds of loss of loading behind the rear axle. Why didn’t the handling balance change with such a large loss of rear loading and dramatic change in front to rear percent? I thought – the same as you are probably now thinking – there must be a reason why such a dramatic change in rear weight, front to rear percent, and overall weight does not seriously affect the handling.
