Hi, I have a 2006 jeep grand cherokee laredo 4x4. I am looking to get a brush guard, sidebars, roof light rack, and some nice wheels. Any suggestions for these parts would be greatly appreciated.

I'm new to this stuff though and I don't know how big I can go with my wheels without having to lift it (that would cost a little to much for me at the moment). I still have the factory 17x7.5 inch wheels but I was looking at

which come in 18x8. So my big question is, what would I have to do to get these wheels to work for me, if indeed they will work at all.

Thanks in advance
