@ 3stagevtec, good info there!........ is it OME962's you had on?
For the Gen 1 & 2, imo, the OME + coil spacer seems to be a better buy than the Calmini. The plus is that you get to mix and match springs for your application (winch bumper, long range fuel tank, rear steel bumper, etc).
I don't think Calmini will sell you a diff-drop bracket alone, however I found aftermarket diff-drop brackets
here. Or maybe if you have some skills, you can fab your own bracket.
Regarding shocks/struts, I have seen an OME front strut fail.
Oem length Bilstein Monotube
Front struts for Gen1 (should fit Gen2 non-ABS), couple these with strut spacers and you should have a very good front strut.
For rear shocks, I have been doing some googling, and found these
Bilsteins. 2" longer travel than stock.
(These are what I used, posted in the Bilstein shock info thread. On full shock extension jacked up, the rear coils unseat from the axle spring pad by 0.5" using these shocks).
There is a steel housing front diff I have seen on the internet. Some say it is from the V6/ diesel Vitara*. This should be the best upgrade for the alloy diffs.
Also for Gen 1, there's a rear axle joint spacer to correct the upper joint angle when lifting the rear.

On my application, (Escudo SWB), using the G.Vitara SWB coils (1.5" longer), and the rear Bilsteins. Ride is a bit firm with the rear shocks, might help if I use a rear steel bumper for extra weight. Did a "
strut mount flip" to compensate for the lift I have instead of a strut spacer.
Using Oem 16x6.5 alloys with 225/70R16 BFG Long Trail Tour with no rubbing, even with a 1" wheel spacer.
235/70R16 had fit when I had a 2" body lift (removed body lift) and sure it would fit with my current setup.
If I didn't source those G.Vitara SWB springs, I would have used the coil spring spacer kit for now until I got OME springs.
