12" rock star wheels with sand tires, bolted right up to my xtz, had to grind very little off the front calipers, back ones went right on with no interference problems.
Just get ahold of Xtreme tire co. Phoenix, Az. they will hook you up
Who doesn't condone it? Maybe the people who sell caliper relocating kits or spacers. Personally, I think a little grinding on the caliper is a much better option than spacers. And it allows you to get a sand set for a lot cheaper than going the 14" route.of course no one here condones this in any way, but I thought I would add the pics for you guys
