I just scored a 2008 650 prowler that was already converted to a 4 seater for my wife to enjoy riding on trips to the dunes. The prowler is bone stock otherwise and I have read the mud clutch is the way to go for the sand but dont want to have 2 sets of tires and wheels laying around. I was thinking the sti mud trax tires. What other mods do you recommend? My wife is no dare devil but I want it to be fun for her.
