I have the 6" Fabtech kit on my truck with 38x15.50's and love it. I had it installed in Nov.. The truck is my daily driver and I put around 500 miles per week on it. There have been no real negative issues with the lift. If there is too much roll in the corners for your liking then put the shock hoop on the front it made a big difference on my truck.
It is all relative to what you are looking for in your H2. I didn't think the H2 was a luxury SUV when I bought it. Everything in the damn thing rattled. If you want a nice SUV then leave it alone or buy an escalade. Do what ever makes you happy because you are the one that has to drive it every day. The lift and tires sure do get you a lot of looks from other cars on the road
