Flush setup for OEM wheels (17X7 +48) is
F 17X7 + 28
R 17x7 + 23
This mean 18x9.5 +40mm with stock suspension.
F will poke 19.75 mm
R will poke 14.75 mm
In the other word, 18x9.5 +40mm wheels will look like the same as you add 40mm spacers to OEM spec.

Another example of popular wheels Wedsport TC105N 18X8 +42
If you understand the caculation, you will know how much will poke or stick in for front and rear. The answer is
(((8-7)x2.54)/2)X10 + (48-42) = 18.7 mm
F will stick in 1.3 mm
R will stick in 6.3 mm
So Wedsport TC105N front is almost flush but you may need to add 5mm spacers to get flush in the rear. Or try to find wider section width tire if you dont like to add spacers.

Here is a pop quizz. 18X8.5J+45 Will this wheel stick out or in?
LOL.... I didn't even look at your math. I don't think flush is 17X7 +28 and +23

I have the wheels and wouldn't say they poke out 19+mm in the front and almost 15mm in the rear.
