i think 18s are too big unless you do extensive body mods

18's are to big, i thought 15's were just alittle to big but ok. you may probs get pulled over for it. Ride hieght would be high as even with low profile, get a lift kit then you can fit 24" if you still going to do then do it! its your car and also im curious, never seen 18's on a 1200 ute before.

i like modifying the #OOPS# outta stuff too... but each in its own era :)

yeah 18s will go but as most people have said you will need to make the inner and outer gaurd larger in to front make them fit . the coupe has a larger rear wheel arch aswell so yours being a ute you will need to stretch the rear wheel arch to fit the larger diameter even with the lowest possible profile tire. there is a ute that has had 18s on the back and 17s on the front that i know of but i have never seen another 1200 with 18s all round apart from my one . i could be wrong though .
