Im thinking about giving my Sammy a 3" Calmini suspension lift. The Calmini catalog says I can fit 31's with this lift. Would have to modify the bumpers to fit the 31's without rubbing? I am also going to get 5.43:1 gears, would 5.43:1 gears be the best choice for 31's? If anyone who has done this kind of setup could give me their insights, it would really appreciate it.
