this isnt the thread for that question. you should search and see what others have run (since no one has posted such setup in this thread yet). this thread is mostly just to be a guideline, not a definitive answer on what will or will not work on your car.
but mostly it will depend on a lot of different variables that come into play.
what offset are the wheels? what suspension mods do you have? how low is the car? what are your camber settings? what tires are you running and in what size? etc. all of those things come into play. but with 18x9 i would probably expect to roll the rear fenders, at least from what ive seen.
