Offset recommendation

djpathfinder

The OEM 19" Rays are:
19x9 +47, 19x10 + 30

At stock height it is popular to go with 20 mm front and 25 mm rear spacers to get a flush fitment. That makes the "effective offsets" F: +27 and R: +5. 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: +33 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=)

First of all, sorry, I made a typo...I meant F: +33 (not +31). My original post will be corrected to reflect this.

OK, what do you mean by "regular look"? Are you referring to stock offset (wheels are slightly sunken into the wheel well)? By "flush", I mean pushing the wheels outward so that the edge of the wheels/tires line up with the edge of the wheel wells.

If you go 19x9.5 and 19x10.5 +18, your front wheels will stick out about 15 mm beyond the edge of the wheel well (too aggressive), and your rear wheels will be recessed approximately 7 mm from the edge of the wheel well...the rears will look OK, but the offset could be a bit more aggressive. Front and rear offsets in this case will be mismatched.

F: +33 and R: +11 for a 9.5" wheel width at stock height and camber will yield desirable results. Of course, give or take a few millimeters is acceptable.
