oh and one more thing that really gets my goat about my adopted wheels is the center caps bolt on with 5 tiny allen screws and to get the lug wrench or any socket to fit the lugs you have to remove the center caps!

 

I see you don't have any pics on your profile. ...I'd love to see what your car looks like. Do you have any pictures you can post ?

 

i would definatly go with the 9" wide rim. besides, i dont think that you can get many aftermarket rims in 8" wide anyways. i would go with the 9" up front and the 10.5" in the back.

 

here is a pic, hope it works. I have never had much luck posting pics on here

 

9's up front

 

i run 17x10.5 and 17x9 up front. no problems here.

 

I run 9's up front, I need to run 9's all around next time, the 315's are fun but they kind of promote understeer.

 

I have 17x10.5(315/35) in the rear and 17x9(275/40) in the fronts. This look by far favors one of the most aggressive looking stances you can give your stang!

As a side note I had heard some people who run the 275's up front, had trouble with some rubbing issues at full lock to lock. I am happy to report that IS NOT the case with me. I am also not lowered yet so I am not sure if that will make a difference? Last night while I was out in my Stang I tested this known problem that a few of you guys have experienced, just to see if my tires would rub...but I usually don't have to turn the steering wheel that far in the first place...but just a little something to remember when going wide in the front?
