I have a Boxster with stock suspension. 996 turbo twists rims (18). I don't have the OEM numbers and offset 8.5 and 10s rear.

Fronts fit with no problem and yours will fit your car.

I tried 11s in the back and the tires rub when cornering. There is an old thread of someone installing 11s with some fender rolling.

I installed the 10s in the back with a 10mm spacer to clear the strut. It works. outer aspect of the wheel looks almost flush with the fender.

I have my car getting some work done far from home but if you want I can take some pics.
