I haven't even gotten it yet but expect to have the same problem as you. I know Patrick's sells rear end kits with just about any ratio you want but they will set you back $650 or so including the installation kit. That seems kind of pricey to me but is probably the easiest way to go. I'll be following this thread to see what others think.
