The GFX kit comes with everything needed to go completely around the car. Each box will contain a parts bag with whats needed to install the item in that box, will be 5 boxes in total.
There are several types of kits, have to be careful to pick what you need.
1) Color, what color you want, incase you want a kit that is not like you cars color like straight black.
2) Model, SS or LT/RS, the difference mainly is what the front splitter will be, as there are 2 types if you have seen the different ones on other peoples cars, the rest of the kit will work on either car.
3) Exhaust type, performance type(NPP) or non-Performance(standard duals), this will determine how the rear GFX kit will be to accommodate the exhaust tips. Note, the non-performance one will require cutting the tips off of your muffler and adding new ones to work with the new rear valance.
They are pre-painted to match the color you pick so you can bolt/drill/rivit straight on. ( rear bumper disassembly required)

This is the rear of my car, i do not have the performance exhaust(plus it is an aftermarket muffler), so this is how it would look. Mine was 84116166 , which is SS gloss black.
