==Nose weight vs. tail weight== | ==Nose weight vs. tail weight== | ||
| − | '' | + | For a drag car, nose weight is undesirable, while you want as much tail weight as possible. Nose weight is the amount of weight located over the front tires. Tail weight is the amount of weight located over the rear tires. Most cars have a balance of 47% to 53% ratio, with the front being heavier. A lot of cars have the battery, radiator overflow and some other essential items located under the hood. Moving the battery back to the truck area can help the weight precentages favor the rear. Your typical drag car would want 53% rear weight with a 50/50 split on the left and right weights. Here are some items that you can replace with its lighter counterpart. |

| + | ==Sprung weight vs. Unsprung weight== | ||
| + | Sprung weight is anything supported by the suspension, Unsprung is anything that is not. Removing one pound of unsprung weight is approximately equal to removing ten pounds of sprung weight.''(this statement needs verification)'' | ||
