I'm running 22x10.5 wheels with lowering springs up front and lowering links in the rear because I have rear air suspension. Nothing to it, no advice to pass on, just do it and get an alignment, click on the link to see my pics in post #1588. Eventually I'm going to go with a coilover setup, I want it a little bit lower...lol!
