I have the LSR +3 kit and love it you get 10-11" of travel with WERs, I can and do ride as hard and fast as all these guys and the mid travel has never been an issue...plus trail riding there is lots of times where narrow has been better. Yes, it does increase your ride height about an inch(11" front 10 3/4" rear).
I dont think you can go wrong with lsr kit, Ishock is a little slow to move on things sometimes. I know steve at makin trax has lsr kits at great pricing. But more importantly know how and good personal service. I would at very least call him and get his input. He does not bite...LOL
