For a 09 I would go with the 18's.

18's as a good balance between tire options, performance and looks.
19's if you don't mind spending $$ on rubber
20's if you don't mind spending $$ on rubber, you like big wheels, and show>performance

I'd say 18's, that way you can keep a meaty amount of rubber under that stang.

The drop will make the ride more ridgid all on its own...18's fursure!
Rubber is your friend

ok man these are the ones i want. either 18 staggered 10/9 or 19 staggered 9.5/8.5 what do ya'll think i liek the 18 cause they are wider in the rear but it's only .5 so it shouldn't be that much of a diffrence.

will 19 be right with a 1.5 inch drop or will i get rub

BleedinBlue

You won't rub. The width difference in wheels won't matter, it's all about the rubber.

i think all i care about is if the wheel/tire width goes oues to the edge of the body. so from behind the wheel does go way in from the body
