19's In the Rear 18's up front or 18's in the back 17's in the front?

[SAMO]

Ive recently purchased a 04 gto yellow as a freakin bumble bee but ive been searching for rims and i kinda like the old look with the back end raised slightly to give off that feel of greatness ya know? but Im unsure what size tires i should do if i do 19's in the back and 18's in the front or 18's in the back and 17s up front. if anyone have any pics that could give me a good idea that would be great also i really dont wanna attempt to get the fenders rolled so the tire sizes would really help out a ton. cause i llike the wider tires but if they are more for show and wont make a difference then ill jus stick to the standard 8 or 8.5. thanks

I suggest staying one size wheel and then figuring out if you want to go staggard or not...
