First, if you think you MIGHT go to a Calmini Anvil (STEEL front axle housing), go with the Calmini 3" suspension lift - it's required.
My VERY FIRST mod was the Calmini header for the 1.6/16 valve - I also put one of these on my daily driver (a 4-door 95 Sidekick).
Next was the 6" Calmini combo-lift, the Calmini front winch bumper, and a Warn M6000 winch. Warn premium manual hubs. Then came the rock-sliders - I had mine custom built by Spidertrax. Then full belly armor, and steering stabilizer. I put Goodyear Wrangler MT/R's - 31 X 10.50 under it, on 15X8" rims with 2-3/4" backspacing, from Spidertrax. The Safari Snorkel came from Rocky Road.
When it was available, I got the Calmini rear swing-arm bumper, and when they FINALLY released the Anvil, I upgraded to 26 spline axles, 5.83 R&P's and ARB Air Lockers front & rear.
I just got my Calmini 4.24:1 Transfer Case gears last night. Still need a roll cage, a new clutch, and new exhaust. Oh, and a bikini top. And a Tuffy 063 Oversized Security Drawer, in the place of the back seat.
