Lowering shouldn't really be all too difficult, but you'll be dealing with air-ride... LRR tires, IMO, still aren't worth what you pay for them, especially in larger sizes, especially when you compared them to any "perma-mod"... LRR tires are great, but they only last until the tire is dead, then you're out another $1000. Not exactly economical, when you can get a good, hard, standard tire w/ a 50k mile warranty for like $125 (for larger sizes), then use the extra $400 per set of tires to pay for things like fuel, and other mods.

Driver modding is by far the best thing you can do... anything you can do to just drive more efficiently will help the most of anything, and will show greater returns on other things you do.

I recommend a full belly pan along w/ the grille block.
