Hi!

I large part of the advice needs to include WHY you are modifying it.

You can fit 31's w/o a lift for example...its only a tiny bit larger than the stock tires.

You don't want a brush guard, at all.

A real metal bumper, like the ARB you mentioned, would be much much better.

Also consider for example:

Sliders are a great first mod too, as you really need them to off road.
