There's always more to do to a car! For a starters he forgot the very very first mod, a bash plate! Longer travel coilovers would help massively. An L series low range would be an upgrade. Rock sliders would help if he wants to do larger rocks without panel damage. And then there's all the personal touches you do over time to tweak the car the way you want. But personally I like to test each new mod one at a time so that I can appreciate each one individually. I also know where the weak points are each time so I know where I want to improve next to get the best value.
