Noob Needs Help w/ Offsets :(
OK... I've PM'ed about a dozen of you guys... When I start to think I'm understanding... I see someone else's wheel specs and I'm thrown for a loop...
I understand what they are. Here is where I'm having issues:
I'm having a hard time relating the offsets of a 10.5'' width wheel (most common rear width here) with a certain offset and applying that to different widths.
I see one wheel and offset I like in a 10.5'', then I see someone post a 11.0'' rear width with a totally different offset that looks just as great and I try to think, "Ok... but if I want to stick with a 10.5'' width... how do I add/subtract the offset to get that look on my skinner wheel?"
I hope I'm explaining this well enough. Perhaps it would help if someone told me what is "flush" or the "perfect" rear offset would be for a 9.5, 10.0, 10.5, 11.0 to give me a 'hellaguide' (if you will).
The fronts seem to be easier to figure out because people stay closer to the 9.5'' wide area... but the rears people run everything from 9.5'' - 12.0''.
It would also help if someone could once and for all tell me if the G and Z can use the same offset wheels and the fitment look the same? I've been told G's need to a run 10 offset "tamer" than a Z's wheels and I've been told they should fit the exact same.
ARGH! TIA!

It's easy bro, for every 0.5" width it's about a 6 offset difference (sometimes 7). As you get wider, you increase the offset by 6 for every 0.5" to get the same effect. As you get narrower, you decrease the offset by 6 for every 0.5". Example:
19x10.5 +0 would have the same effect as 19x11 +6 and 19x11.5 +12, etc.
There is a little variation, sometimes the offset goes up by 7 when you increase width by 0.5" but you don't have to be that exact. This is the general rule of thumb that I use and it's easy and simple. Correct me if I'm wrong people but this is how I understand it.

Hmmm, that was not my experience. I went from a 19X8 +30 to a 19X8.5 +38 in the front on my new wheels and they are considerably more sunken in than the previous rims.
Maybe I misunderstood the math.

but depending on what size tires you were running with each wheel setup, it may have made it look like it was sunken in more than it was.

Like patman said, the difference should be very minimal (1-2mm). Besides tire size, camber is also a factor.

Awesome! Thanks guys! I was way off.... I was thinking 15mm = 0.5 inches.. so I woulda been really messed up, lol.
Thanks! I'll use the 6-7mm rule! That HELPED a ton.
And thanks again to all those who were helping me in PM's... it just takes hearing it a few different ways to get it -- especially over the internet!
