Hello - I have a 2 Dr JK with some mods with some weight; Oil Pan/Trans Skid, Steel Front & Rear Bumpers, Winch, chains, Side Rails, etc. I plan to offroad. I have a 2.5" Teraflex Budget Boost w/ spacers & VSS 9550 shocks (std in that kit). I want to put Rubicon Express coils on with the VSS shocks and mount 33" tires on my AR 16" x 8" rims. Would the 2.5" RE Coils be the best way to go? I also have some Daystar 3/4" leveling spacers. Can those be used if one end sags a bit? Rear is a little lower now.

 

I don't know much about the RE coils but IMO almost any coils will be better than a bb. You'll gain more off-road performance and a better ride. The Daystar leveling kit can be used with any coils.
