First off your car does not have a frame it has a unibody.

Second of all if you were to cut the chassis to fit those rims then you would be losing structural integrity. This in itself is a curable thing through caging and structural reinforcement (buy a tube bender, a welder, and some beer). Hopefully you know what you are doing when you take on this task...of course from your intitial post I am going to guess that you have no clue at all so you must post pics of the car after it falls in half from stress fractures.

Third those rims look ghey on that car as does the hood scoop.

I am done have a nice day.
