For a little more info, sportcross tire clearance is exactly the same as the sedan, I had a sedan first. My rear fenders are rolled with a very slight pull, and the bumper tap is trimmed. I'm running about -1.2* camber in the rear. If you want wide tires, you need a wheel with an offset in the mid to high 40s.
The CR Kai I used to run were 18x9.5 +38 with 265/35/18 kdw2's. I would rub on bumps when I had people in the back. Now I have the 17x9.5 +44 xd9's with 265/40/17 dunlop z1 star specs, and have absolutely no rubbing even when I jack it up by a front corner to test clearance. I have also run 17x9 +45 rpf1s with 275/40/17 Kuhmo ecsta xs(no wider than the 265 star specs) with no rubbing.
Also, keep in mind that not every 265 is created equal, having all three of those tires next to eachother, I think the 265 z1 star spec is the widest, the 275 ecsta xs and 265 kdw2 were about the same size, just a tiny bit smaller than the star spec.
