Wheel stud patterns, offsets, etc

[A.D.D.]

I'll start off by saying I swear I've searched the forum and the net for about half an hour with very little luck.
I'm trying to find out what my AE92 stud pattern is (think I found it was 4x100), and what this wheel offset business is.

I know what the 4 studs means, but what's the x100(mm?) bit?

I bet that the offset refers to how wide the wheels sit on the car, but is there only one offset that each car model can take?

Thanks guys

read this to understand PCD/Stud Pattern http://en.wikipedia.org/wiki/Wheel_sizing#Bolt_circle

and the link from johntramp will help you with offset. if you want to know if a new wheel will fit, obviously the PCD has to be the same, and you need to know the original offset and the offset of the new wheel, and be able to measure stuff (so you can check if stuff will clear on your car) ie the offset calculator will tell you how much more the wheel will move in and out and you need to make sure it will clear the shocks and guards

Thanks for the help guys. Makes it all clear as.
But still one more thing, any estimates for what the offset is for the standard wheels on my AE92 Levin?
I couldn't find it printed on the wheels. They're just standard 14" wheels with hubcaps.

theres a howto on measuring offset, that will get you close enough to work from
