Thumbs up Offset question...

Ok, here's the deal...

It seems everyone is posting that they have higher offsets on their rears than on their fronts. I don't understand this, does someone want to explain it to me.

Every pic I've seem of S2K's with rims that have lips have a larger lip on the back than on the front. Also, when you look at pics of people running SSR Comps, you can clearly tell that the spokes on the rears cave in towards the hub whereas the fronts bulge out.
This would all indicate to me that the rears have a lower +offset than the fronts. What is it that I'm not understanding correctly? I somehow doubt that everyone is wrong about their offsets...

Oh and By the way, what are the stock offset on the AP2, used to know, don't remember and search isn't working too well.

Thanks

They post this because that's the way it is. We run staggered widths for rims and tires. The rears are wider than the fronts. In order to "tuck" them into the bodywork, the rears need to have higher offset or they'd stick out. I'm not sure what you are seeing and exactly what you mean by "caving in" and "bulging out" but it could be an optical illusion.
I seem to recall that the offsets are the same from AP1 to AP2. I think they are something like +55mm front and +65mm rear.

In case you don't know what "offset" is, it is the deviation of the mounting plane from the midline of the rim. Plus (+) would take the mounting plane towards the outside of the rim and minus (-) would take it towards the inside. The wider the rim, the more you must move the mounting plane to the outside so the rim won't stick out so far.

Yep, know what offset are.

Wasn't even thinking about overall rim width, that was my problem there... duh

Thanks for helping me make myself look stupid Xviper.

Yep, I get that, and if the fronts and rears were the same width the rears would have a lower + offset or equal offset to the fronts.
However, since the rears are wider they can have a slightly higher + offset than the fronts and yet still have a bigger lip.
I guess I had just not fully put my brain into motion before asking my question.
