i posted a thread about wheel sizes a while back. The wheels you are looking at based on the sizes (19x8.5 and 19x9.5) will work, but in order not to have to modify anything, going with a low 20's offset all the way around is what you want.
Most will tell you that you should go wider for a better stance (19x9.5 and 19x10.5). The size of the ones you are looking at is the same that i have and i believe the same as the 18's as well (as far as width). I have the oem rays wheels.
heres the thread for reference of wheel sizes and what people told me....
i need wheel sizes.......
