2013 Subaru BRZ with Gram Lights 57Maximum

I put about 30 miles on the setup and only experienced slight rubbing when I had the wheel turned all the way to the right driving in tight circles (this didn't happen when turning left). The car is still on stock suspension and I think this combo might rub the fender if lowered since the tires stick out a little ways from the fender. Also, I think a +42 or 40 offset would be better for this combo of width and tire. I'm planning on refinishing the wheels, since several have curb rash, and going with a 225/40/18 or a 235/40/18 street tire when I get back from a TDY in August.
