I'm planning on ordering wheels for my '15 ecoboost and I'm not sure which offset I need to have them flush with the fenders all the way around. Here's my options:

19x9.5 w/ 35 offset
19x9.5 w/ 22 offset
19x10.5 w/ 22 offset

I don't have the performance pack so I shouldn't have to worry about clearing the brakes. Also, I'm loweres 1" on SR springs.
Opinions on which setup to go with? I think I would prefer 9.5" but what's everyone think?
Thanks!

The 19x9.5 with 35mm offset should fit great.
The others, especially the 10.5 will poke out beyond the fender.

 

There is also a 20 x 10.5 w/ 30 offset. Opinions?

 

Just about as bad.

You need to look for offset in the 40+ mm range if a 10"+ rear wheel is used.
On my '13 a 20x10 with 48mm offset and a 305/35/20 rear tire fit perfectly inside the fender.
On the '15+ body you can get away with a few less mm offset, but not 15-20, so try to stay around 45mm offset if looking at 10.5" width.

 

These are 20x10.5 w/ 30 offset and they don't seem to poke too bad. I'm wanting 20" to close my fender gap a little. That little bit of poke is worth it to close the wheel gap I think
