I love those wheels - to me they are classic Jeep and really make any Jeep look great. I put a set of 2005 TJ Moab's on my Liberty and have thought about putting a set on the XK.
To your original question, I saw somewhere that the amount of grinding on the calipers is very minimal. Just the top and bottom corners and with a good 4" grinding wheel shouldn't take but just a few minutes.
Here's what my Liberty looks like with the Moabs:
2006 Limited, 5.7 Hemi, Tow Package, SuperChips tuner, Full Skids, RER MyGIG Upgrade. OME HD Springs w/ Bilstein 4600 shocks
