Hi, I am always confusing with those offset numbers?
What are they stand for? +? -? 0? which means wider or narrower?
Thanks.

farkkk...i did just reply and it got canned on submission...
anyway (again)
offset is measured from the longtitudinal centreline of the wheel, inwards or outwards to the hub mounting flange. +40mm offset means the flange sits 40mms OUT from the cetreline of the wheel, making the wheel generally sit deeper into the body. -40mm offset see the flange lie 40mm IN from the centreline of the wheel, making the wheel as a whole poke OUT from the body of the car. 0mm offset has the flange bang in the middle of the wheel.

The offset is the distance between the mating surface of the wheel, and the centreline of the wheel. So a zero offset wheel has the mating surface right in the centre, while a +20mm offset has the mating surface 20mm towards the outer edge.

Thanks.
so + means narrower, and - means wider.
ok.
but why is the standard AE86 wheels has -27 offset, but they sits quite deep into the body.

No, it has nothing to do with the width of the rim - read it again!

I mean narrower is more towards inside of the car, and wider means towards outside the car, rite?

The term your using 'narrow and wider' is a reference to the size of a rim. 7,8" would be wide. 5" is narrow (in respect to 15" rim).
The only terms for offset are + or -.
You will only confuse yourself and other by using the term 'narrow' or 'wide' offset.

so putting - negative offset rims will give you a wider track overall and narrower for + offset.

Umm not that simple.
You need for wider or narrower track, you need to base that upon the original offset of the rims, and the width of the rim.
Consider this:
13x5 +23 I think.
from 2.5" centre you are 23mm =86.5mm from bolting flange to inside of rim
but 15x7 +23 =111.9mm from flange
You need to consider both rim width and offset.
If both rims were +-0mm, then the story would be different.
