I grew up near southern/middle, IL and know of a couple guys in that area with Sami's, good times !!
How much money are you looking to spend ?
How much of the work and mods can you do yourself ?
This will be a huge factor in your build.
The best ride I have found out of a Sami
is spoa with YJ springs.
I haven't tried coils but I have heard they would be better but a high dollar mod unless you can do it yourself.
A shackle lift will only give you half the lift as what the length of the shacles are... So a 3" shackle will give you 1.5" of lift.

They claim it helps but I haven't tried it.
1.6 16v engine is a GREAT mod to these. It really wakes them up.
I added a set of speakers right beside the rear seat into the side panels.
Places to find parts (also think junk yards too)

Tires, Lockers, Gears.... Some guys do ring & pinion and/or t-case gears.
Keep in mind the effects of gearing on your speed and rpm since you want to keep this as a dd too.
Good luck on the build. These little things are tons of fun.
