Hey,
I just got an 09 RZR and just put 27/8/12 ITP 589"s up front and 27/11/12"s on the rear on Motorsport alloy rims with -47 offset.  The front tires rub a bit.  I was thinking of putting on the 3" lift kit from sidebysidesports.com but have heard that there have been problems of shaft binding and breakage.  I see that you have put this kit on.  Any problems or mechanical failures?

Thanks
