I say go with hybrid rear springs up front and a longer lift spring out rear. Wheel spacers IMO shouldn't be any wider than 1.5" because you have alot of leverage the further you go out, which in turn stresses out the R/P, axles and locker and housing. And in regards to the brand I'd say Marlins but it really doesn't matter really because I've ones from each company and don't really see a differance with any of them.
