Get it wrong and your wheels can scrub against the bodywork, suspension or at worst not turn at all! Secondly it determines how the suspension and self-centering steering behave. The most obvious problem that will occur if you get it wrong is that the steering will either become so heavy that you can't turn the steering wheel, or so light that you need to spend all your time keeping it in a straight line.
this is from race and road


Zero offset: The hub mounting surface is even with the centerline of the wheel.
Positive offset: The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front-wheel drive cars.
Negative offset: The hub mounting surface is toward the back or brake side of the wheel's centerline. "Deep dish" wheels are typically negative offset. Offset can be calculated by positioning the wheel on a flat surface and measuring its overall width and backspace as shown below. Divide the overall width by two, then subtract this result from the backspace value.

1. To compensate for a wider wheel: A wider wheel with the exact same scrub radius as the stock wheel will be positioned closer to the suspension components. If the wheel is too much wider, it will not fit. To compensate, you would choose a smaller offset to move the wheel away from the suspension.
2. To create a wider stance: By setting the wheels outward, the stance of the car becomes wider and stability is increased. In some applications, the benefits of this stability are greater than the drawbacks of the scrub radius change and the driver may make this compromise.
3. Looks: A smaller offset moves the wheels outward, so they have a tendency to fill out the wheel well better. Cars set up for show, more than performance will often choose a lower offset wheel, however, if the offset is too small the sidewall will rub the inside of the fender.

this is why offset is important.. bottem line, its status and thats all you really need to know.. 0 = good.. + = generally not good.. at least for the 240's
