9" will probably poke and require a lot of fender massaging/camber. I am running 17x8 +52 with tokicos and it required a spacer in the rear to clear the strut.
horns, do you have BCs as well? Or stock struts? I am under the impression that the stock struts are larger diameter and therefore rub on wider offset wheels.
I have a new set of BCs in the box in my garage waiting to be installed, but right now I am on Tokico blues and Tein S techs. The coils are much smaller than the stock struts and allow more clearance than stock struts, but it is not a significant change. The wheels still have to fit under the spring perch of the strut.
