Advice on build list for the next year

My advice would be fit some good quality 215/75s because that size fits and works great on a standard Jimny (as long as they aren't remoulds). Fit them on the standard rims. Don't fit wheel spacers because they will make the tyres scrub the arches and throw mud all up the side of the car, onto the mirrors, door handles etc and it's really annoying. You don't need any lift with 215s either so no need for castor correction. Lights, snorkel, bumper etc is all your preference. I find driving lights in the bumper can be useful but lights on the roof make it harder to read the road surface so are rarely much use when driving. They also get caught on tree branches and break off. A snorkel is useful if you intend to go through water deeper than the top of the tyres (over 2ft deep) but you will also need to fit extended breathers for the diff, transfer case and gearbox to prevent water damaging those things.

That's all from my practical point of view. If you are going for a certain look then obviously fit whatever you want to achieve it but bear in mind that, as Lambert says, cheap mods rarely improve anything.
