17x8.5 +5, 17x10 +10 Will they fit?
 

How will this wheel set up look?

Roll/pull fenders, lots of negative camber, 205 and 215.

Exampel:

18x10 +25F or +20F
18x10 +15R
Nankang 225/35/18

Lots of negative camber.

You'll be 5mm more aggressive in the rear than that setup.

8.5 * 25.4 / 2 - 5 = 102.95

10 * 25.4 / 2 - 25 = 102

So 8.5 +25 will be the same fitment as 10 +25 up front.

go for it should be fine

I was going to do 10.5 +20 in the rear

but yeah for sure camber and light pull to be done for the rear
or vice versa less camber more pull which I've seen soo many do.
