THE CONSEQUENCES OF TOO MUCH POSITIVE/NEGATIVE WHEEL OFFSET. If your wheel offset is overly positive, you run the very-real risk of having the wheel sit too far inside the wheel arches, causing the inner edge of your wheels and tyres to rub against your suspension components. As if that wasn’t bad enough, this rubbing can cause serious damage to your wheels, tyres and suspension. It can also negatively affect your car’s handling, making it potentially dangerous to drive. On the flip side, too much negative offset will push your wheels and tyres outside of your wheel arches. This won’t cause as much of a problem as too much positive offset, but it will make your vehicle look fairly silly and might require you to roll your arches, or fit arch extensions to cover the wheels. succes !!!
