I'm interested in seeing pictures of this, and i'm not trying to bash but that is more lift and money than it's worth considering I run 35x13.5's with 2" of lift, no sway bars and no rubbing even fully turned at full flex. If i needed 8-10" of lift i'd probably be running 44's or some monsterious size tire that i would then need bigger axles for anyways.
Now a 8-10" lift for the pickups, sports and Gen 3s would be more reasonable considering they need more lift to fit bigger tires. I really hope you sell some of these kits because i'd like to see some monteros on 40+ size tires but i think they might be tough to move.
