I have an article somewhere on a turbo with 10x18 rearwheels with 285/30x18 tires. Have tried looking for it, but I have quite a collection of car magazines so it's not exactly easy to find
 Anyway check JackOlsen's posts. He has really big wheels.

I'm going to be running 11's with 315's, adding a one inch spacer to clear the headers and oil lines.
But my car doesn't have Turbo hubs, so it's hard to say what will work on yours.

Jack, when you add a 1 inch spacer, could you instead "add" 25mm more negative offset? ( if you could specify this when ordering)

Well, we had to build the wheels before we put on the flares, so the one inch of spacing was to give us some play in fitting the new wheels. The new wheels have 6 inches of backspacing. If I did 7 inches of backspacing, I would definitely have some contact issues with the exhaust and oil lines.
But my car has RSR flares, which aren't exactly the same as a Turbo's, and I have the 72 oil tank, which puts things in different positions. When you're getting this big, you've got to make specific measurements for your own particular car.
