Check out Mountain Machines Performance. I have PEM wheels and a 8" 2 inside conversion axle for the 03 F7 from them. The wheels seem pretty good but that axle is a real pain I had to do some filing to get it all to fit even though it was designed for my 03 wheels and the instructions were horrible. I'm pretty sure HiPerf is just selling there left over PEM stock.
I picked up a axle from Mountain Machines Performance to convert my M6 to two inside 9" wheels this weekend no instructions just what they told me at haydays and I had it in within 15mins no modification neccessary and that Freedom axle looks pretty sweet to.
