Picked up my new project today Lift Kit?

[fishbones]

Got my new project cart today. 94 DS 36v stock.
Ordered some 22x11-10x8 5+3 tires and wheels and I was thinking 4" or 6" lift kit. Is there any advantage to one or the other or is it just looks?
I have read dozens of posts here about lift kits and one will say jakes is good and another will say its not all sports is better, any experienced suggestions would be appreciated.

Also, is there an incremental path to upgrading the torque on these things, I mean instead of going 48 and re-doing it all (probably should have bought a 48V).
Is adding a controller and increasing cable size enough and maybe later when I need to replace batteries make the big move?
Coughing up over 2k to replace motor, controller, F/R switch, cables, batteries and new charger is not in the budget yet as I am already dropping $1500 in cargo box, tires/wheels, lift, HD rear springs, lights, camo wrap, black seat covers etc.
Many thanks. Fishbones
