if you are stock height, then more likely then not - unless you find a way to bottom out - you won't rub. As far as offset, +45 is the best way to go. If you go +37, you might have to have spacers; and definitely a fender roll if you get some lowering springs. At a +25 offset, I wouldn't chance it, unless you have a fender roll, probably some spacers, and adjustable ball joints - like I am having to get - on the front wheels.
Adding spacers would lower the offset even more.
