Wheel Offset Discussion Thread... How far can we go?

[cooltoy]

I am a total blank as far as wheel offsets go, so after reading a bunch of threads, I still have some questions.

To start with, I am not looking to do anything extreme, just improve the stance slightly.

It seems that the consensus is that to get a nice more or less flush look the following is ideal:

19x9.5 +22 (front)
19x10.5 +12 (rear)

First question would be is how would these numbers be affected with narrower rims. Say 19x9 upfront and 19X10.5 rear?

Second question/comment - I assume the wheel diameter has no effect on width and offset on the stance.

And third - how would these numbers compare to the "ideal":

19x9 +25 (front)
19x10.5 +25 (rear)

I am not sure how the different width effects the stance on the front, but I would guess I need to use a 20 mm in the rear reach "ideal".

Correct me if I am wrong, but the above front wheel would be like running a 15 mm spacer on sport wheels and the rear would look more like the rear Nismo wheel without spacer.

Please set me straight.

Thank you.
