So you enter in a 7.5" wide rim with a +45 offset, and a 7" rim with a +42 offset. According to the calculator, the 7" +42 wheel will have 9 mm more clearance with the shock housing, and 3 mm more clearance with the outer fender. Quite handy.
Think about it this way: the higher the offset, the further the wheel gets "pulled in" towards the car.
The offset is the distance between the hub mounting face and center line of the wheel. The link I posted above should give you a decent explanation of what exactly it is.
Ok, cool. SO what is the stock Integra rim? I know 6" but offset?
