Here's a pretty handy little tool that should help people out when selecting new wheels.

Offset Claculator

The stock wheels are 6.5" wide and have an offset of 38 if I remember correctly. Now if someone could go measure the strut/fender clearance we'll be in business!

Offset is how far the mouting surface from the center line of the wheel. It can be positive or negative. Positive offset is when mounting surface is located toward the front or wheel side of the wheel. (outside of the car). The more positive offset, the wheel will stuck inside of the fender well. The less offset push wheel outside of the fender well.
