I'm kinda liking these wheels but the fitment has me wondering if its worth it. I'm interested in 19's so the size available are...

Front - 19x8.5 offset 42
Rear - 19x9.5 offset 40

Tires - I'm most likely gonna go with 245/35 and 275/30.

So my question is if 10mm spacers are used for the fronts... Would the 32 in the front and 40 in the rear work? Is it even worth it to use spacers or go for another wheel?
