Brother in law had his 2012 Rubicon done here; http://www.4wheelparts.com/stores/St...fo.aspx?sNo=21
He worked with Zach who took great care of him, including follow-up visits to tweak some settings.
His Rubicon has a 3.5" Rock Krawler lift and he does some towing and was having issues with the 35s, so he had it re-geared. Ran around $1500.
