Craig, if you want the wheels to totally fill the arches, rears especially, as these often look skinny on 3dr. I'd stick with 215's on the front and try 225s on the back. The 3dr as you know has a very wide arch from outside edge to inside edge and is hard to get full look without cutting away some metal and plastic from the body kit. If you went this route you could then fit spacers and longer bolts to make up the gap and get it looking phat !

I know its obviously different but I went down this route with my ST200 to get the look I really wanted.
