Cooltoy, if you take the +25 on the rears, they will be sunken in 18mm into the fender than my rear wheels:
You will have absolutely no problem with rubbing. I don't rub what so ever with my setup.
I personally would get option 1 and run 255/30/20 on the fronts and 305/25/20 on the rear. That will keep you at the same OD as the factory tires and will make the tires fit square on the wheels with no stretch. Option 1 sucks the wheels 15mm into the fender as compared to my fitment. Again, no issues with rubbing. If you need anymore fitment pics of my car, just let me know.
