have no knowledge on making cars able to drive off road. but want to learn
Trucks:
what parts do you need so you don't have parts busting when climbing rocks?

AWD car (Subaru or Audi or Evo) and trucks:
what do you need to be able to drive through giant water puddles or even through thick mud water so that your car doesn't die in it? (blow something in your engine)
for just going through water that is tire height?
for trucks going through window deep in water?

just seen videos of people busting a lot of parts and messing up their engine from water or mud and don't want that happening to me so what upgrades do you need for this not to happen?
besides lift kits, but better "flexing" suspension is good to know about
again i know nothing so any help is appreciated.
just looking for some fun off roading
