Will the following offsets work on a 2003 Narrow Body 996 C2, that will be lowered 1"?

The wheels were made by cargraphic for 993 narrow body.

#5130901847 = Cargraphic Wheel for Porsche PCD 5x130 / 9,0x18ET47
#5130111862 = Cargraphic Wheel for Porsche PCD 5x130 / 11,0x18ET62

Thanks for any help you can give.

 

That should fit fine....225/40/18 front should be fine but it'll be a little stretched on a 9 wide.
235/40/18 can possibly rub a little depending on camber. If it does rub you can use a small spacer. I used a 43mm off set on a 9 in the front without issues.

 

I was a little worried about the stretch to a nine inch rim also.
I am cautious about getting wheels, as I still have upper strut mounts and drop links to get, before the new sway bars, coil springs and bilsten B8s go on.
I might be putting the cart before the horse, just didn't want to pass on the wheels.
Thanks for the information.
