Okay I test fitted them. The front tires rub the plastic fender liner at a full turn. What size front tires do you think I should run to eliminate this rubbing? I was thinking 235/35/18 or 245/35/18. Thoughts?

So I have a very similar setup. 18x8.5 all around ET40 with (245/40/18)

I have a 3mm spacers up front (effective ET 37)
and 15mm spacers in back (effective ET25)

I can confirm this setup works great with zero rub. At full lock the tire is about an 1/8 of an inch away from the inner liner.
I'm also on KW V1's

if you want to be square id try to keep the tires the same size.

try a 255/35/18 all around, shorter sidewall
