In setting up a car for handling it's preferable to attempt to attain a 50/50 weight distribution so that all of the wheels share the load of getting a car around a corner as equally as possible. For drag racing, one strives to get as much weight as possible over the drive wheels to help traction. A car's heaviest end is often the opposite of what is ideal, such as a front-engine rear-drive car or a front-wheel drive car.
To try to improve the weight distribution, race car builders have resorted to things like setting the engine back to get more weight where it can do good. This is fine for the serious racer but out of the question for the average enthusiast. But what if you found out about a mod where you could get the same change in weight distribution as setting the engine back 5-10 inches that took very little time and money to do? You'd probably jump all over this, right?
You can get all of the benefits of setting the engine back by simply relocating the battery from the front of the engine compartment to the trunk. This simple mod can change the weight distribution of a car from 1 to 2 percent. This is a big difference that can easily be felt by the driver in terms of less understeer and/ or better traction
