Hey maddog, I know right now with stock offset, my 27x12.5 touch the outside of my exhaust just enough to leave a minor scuff. (Only under compression of the suspension.) I imagine with the big side lug it would be necesarry to run a spacer, or the 1"offset wheel that you are talking about. I'm already running the lift. I'm not sure about losing turning radius. We might not be able to turn lock to lock without some rubbing.

And for you Bubis, I actually worked in a tire shop for 2 years so if you feel like slinging dirt find another post.

 

ive got a set of 1.5 inch H/Lwheel spacers for the rear of the p650.i bought them for my kfx700 but only used them on 1 ride and bought the durablue axle instead.drop me a PM if interested.
