that shit looks awsome, but i wouldnt go with the tires, just the standard bfg at tires for me, now i just got to find some rims and tires and i will be set
if you want to go bigger than what i said then yea...a suspension lift would allow you more modding ability...but a body lift will give you a little room to work...
with a total of 6" you got alot of room to work...with the right rims and tires you could get another 2"...but you got to think is it worth loosing some of your performance...
