Most people here will go with a 17" or 18" most think 20" are to big but don't let that stop you. You can get a good Idea from http://www.tirerack.com
It lets you pick a Mustang S197 body and then puts the wheels on the car so you can see what it looks like. You can even get a car color close to your cars color so you get a good idea what they look like on your car. I went with Polished Aluminum 18" it puts some nice bling on my car. Make it your car pick what you like and do not worry if others don't like them we all have our own Ideas of what looks good.
yeah...i want to get black bullitts with the chrome lip DD. 18x9 in the front and 18x10 in the back...American Muscle is what im leaning towards, what are the tire sizes for these i know it showed them on the website, with for like the 18x9 you get a 275/40 and with a 18x10 you get the 274/40...is it 274 or 275 just an error on the page????
