Hey mike, BARONS makes the dog bones that have 3 settings on them 1) stock, 2) 1 inch, 3) 2 inch lowering holes on them, installed them on my bike I'm not planning on going with a bigger tire just yet. Low &Mean suggests not running a bigger tire with the dog bones, the tire could rub and cause the tire to lock up on ya, they offer a spring that lowers the bike and is stiff enough to keep it from rubbing the tire.
