My fronts should be fine, look at the rears in this pic.
I used to run a 1/8" spacer with the old wheels, I left it off with these. I can just barely squeeze my finger between the frame and the sidewall and if the suspension was really to compress, the outer fender may contact the sidewall. I think the top of the tire will tilt in slightly in lean and really don't think it will compress that far anyway, especially with stage 4 super heavy rear springs in there now. We'll see though.
I'll take the spacers with me to my first event just in case. Thankfully the rear axle is perfectly square and centered in the frame and stays there thanks to the double adjustable roto joint UMI arms back there.
