Okay so, throughout all of us and what we know we can share what all we have experience with and what can fit and what cannot fit the aveo. So I'll start us off!
1. Underglow, you have to get a seperate bar for the back, because most underglow kits come with something bigger that 20 inch bars for the front and back. And I had to go buy a 20 inch for the back so that my exhaust wouldn't burn it and so I would have a place to mount it.
