gram lights 57S 17x8.5 offset?
Thanks all, they are on order
Not the lightest and not forged as Value mentioned, but certainly lighter than stock and very inexpensive compared to everything else and wide enought to run 255 tires and did I foget - they come in bronze!

Made me think twice or hell a hundred times about what color rims I want. 
Why?? you talking about the pics I have?? LoL
I have more on the comp at home. I had 18x8.5 in 30offset on order in the same color and all back in february, and were supposed to be in May, and then June, then July. So I just told them/ Mackin/Ray's to just nevermind on the 18's since they were going to have to make me a set, (i was going to have the first 18" in this fitment/style in the U.S.), I just told them i would just go with the 17" instead, and I am actually fine with them and Love them to death. They are really light compared to the stock's just from picking each up and comparing. I couldnt wait any longer.
I am really happy with my desicion. And to they guy that asked about my tint. It is Llumar 15%.

Who did you order from??

If you take the same rim, say 17x8.5", one with a +30 offset and one with a +50 offset, I will bet that the rim with the +50 offset (subie offset) will hit the calipers. A +50 offset will place the same rim more inwards of the car instead of outside. Of course, the correct offset also depends on the width of the rims as well.
I understand exactly what offset/backspacing is, and I hope I articulated that in my last post.
To help illustrate my point, let's totally ignore fitment clearance issues with the fender or inboard on suspension components for a minute. All we care about is caliper clearance. In fact, let's assume a multipiece wheel and we have unbolted the rim from the center section.
So now we put the center section on the hub and secure it with the lugnuts. The thickness of the wheel center determines how far away the spokes are where they connect, and then their shape determines how much caliper clearance they have... period!
Offset won't change that.

The offset is determined from where the spoke/where the lugnut mount from the center of the rim. There are a couple of ways how offset is determined from how the wheel is constructed. Say the spoke was placed in the center of the rim. Increasing the thickness of the center of that spoke will make for a more negative offset and vice vesa. Another way the wheel manufacturer deals with offset is designing the spokes to actually curve or convex instead of increasing the thickness of the center. Like the +20 “GTR” offset on the Advans, Volks etc. Say the spoke was placed towards the outside of the rim like in the first picture, that would be a positive offset and will determine if the rims will clear the calipers or not.

You said for example, we take a multipiece wheel and take apart the spoke from the rim and mount it to the hub. Then take the rim and mount it to the spoke and the design/thickness of the spoke will determine if the wheel will clear the calipers. Well, where the spoke mounts to the wheel gives an offset for that rim. Depending on where the spoke is mounted to the rims (the offset) will determine if the rims will clear the calipers.
thanks for the pics! the hub is ALWAYS flat against what is labeled "hub side" in that pic. so now explain yet again how the distance from the hub, and with it the caliper, is any different when the offset changes.

They are a vendor on this forum but I don't think their web site works yet.

Calipers go in the hole above the hub and below the edge of the rim and spokes are in front of them. So depending on how much the hub piece is offset you will have more room or less room because spokes will move more towards the calipers or more away from them.
sweet, well were they in stock?? what color did you go with?? excellent choice on wheels by the way..I know you will love them. Just make sure to get some pics and stuff when you get them in and on.

the spokes do *not* move toward or away from the caliper-- doing so would mean that their position on the RIM is fixed. you're looking at it totally backwards... their position on the wheel center / hub is fixed!
bah, I'm done. hopefully at least one person realizes what I'm saying here, but for 99% it seems enough to have someone else tell them whether a wheel fits or not. and I can't say I blame them.

But you guys got me curious now, I firmly believed that offset would dictate the position of the spoke towards the calipers... I guess I'll have to actually read about it to understand.
