1/4" wheel spacers

I have 295/70/17 mud terrains on 17x8 wheels with 0mm offset.

I finally have gotten them to stop rubbing all over damn creation. (Rubbing in the dumbest spots of the wheel well) however, at full lock my tires either are extremely close to or actually are rubbing the UCAs. I tried out 1.25" wheel spacers like a dumbass and they create a whole new hell of rubbing so that's out. I really only need to push the tires out 1/4"-1/2".
My problem is this. I have found 1/4" and 1/2" wheel spacers but they look to be a universal size (108mm center bore). I also have found the proper hub centric ring to fill that gap and essentially make the wheel spacer hub centric, but the rings look thick. Like thicker than 1/4" so it might be thicker than the wheel spacer.

Tell me what to do. Please. Haha

 

Did you ever resolve your problem. I'm thinking about doing something similar.

 

Nope. Probably just not gunna care and wait till I do a 6" lift with 1.25" spacers. Haha sorry
