The answer I was putting up in the F/S thread:
I would hesitate on the tires only because it is 245 with a 50 aspect. That is much taller than what Dave (dawei) was using/suggesting. Also, keep in mind the offset of +42 is not so good. I ran 17x7 +42 offset on 225/45/17 and I had to roll my rear fenders due to very light rubbing. Now put the 50 aspect together with the +42 and you may find yourself getting new tires.
Plus, the 6 will not see a benefit of a staggered tire setup like a Z would.
The rims will work and you'll need to roll the fenders, but 235/45 tires would be the best set to work with in this instance.
