I let a friend of mine place the 32’s off my turbo s on his stock width xp1000. He had zero rubbing issues and liked the added ground clearance. The turbo s wheels are 6+1 offset from factory so that’s the same setup you’re looking into. If you go crazier with the offset you may run into rubbing issues, but you seem set on narrower overall width so you’d be fine with what you have in mind.

 

2019 XPT4 32" Carnivores on 15x7 STI HD9 wheels 6+1 offset (5.5+1.5 actual). Stock widths = 66" front / 68" back >> New wheels/tires widths = 67" front / 66" back. Yes, the back gets narrower since it is designed to have staggered wheel offsets from the factory. You can use spacers, but, to me, its not noticeable unless I break out the tape measure, so Im running it as is. No rubbing or other issues so far. I like having the same wheel on all 4 corners so I can rotate the tires to get more life out of the rears.
