If you are keeping the suspension stock, and going to 19x9.5 and 19x10.5, the offsets you need to achieve the same look as what I stated above is: F: +31 and R: +11. For easy calculation, for every 1/2" increase in wheel width you are pushing the wheel out by 6 mm (equivalent to 1/4"). Therefore you must add 6 mm to your backspacing to compensate.
So this is how I have it translated in my little brain =)
So for stock height it is common to go with +20 in front and +25 in rear.
And adding a spacer in the rear to make it a flush fitment.
I am still bit confused about the effective offset =(;;
So if you want a regular fitment you wanna make it as close as to +31 in the front and +11 in the rear? Am I bit off?

Also how would like... 19x9.5 front and 19x10.5 and like +18 all around would look?
Sorry for keep asking but I still have hard time differentiating in between of flush and regular look=)
