This thread is full of "aggressive" fitments.

Look through and decide which is the least aggressive and will work for you.
I'm personally running 18x10 +35mm right now on the rear, and it's not even close to aggressive. It required a small pull for my set-up, but that's still not aggressive.
Others will say my fitment is no where close to aggressive, because I don't need to run heavy negative camber for them to fit. It's all a personal preference thing.
