i think 19 will look good. i saw 19 on a gtp and it looks like 18 to me lol.

 

ive seen 22s on a monte they look like crap lol, but 19s might not be too bad

 

19's and 20's both look good on a monte/grand prix

 

the rims will look identical to my stockers but bigger. i'd like to get my hands on a lowering and handling kit including new thicker sway bars. anyone else have extremly bad handling issuse's with there base model montes? my car only has 70 km so nothing should be broken, when i do 70km (the speed limit) on a big bypass my plastic mud flaps just drag like there suppous to! and thanks for the positive input guys!
