need help with wheel sizing

[jinos]

Hi Guys! I currently have a 74 911 with a 964 turbo body conversion. It has 17" cup wheels with a 1" spacer in front and 2" in rear. I just found some 18" kinesis supercups that were on a boxster. I tried asking him what the offset was but he has no idea. I even told him to look in the back of the wheel and he insists it only says 5x130. Any help is greatly appreciated.

Most likely an ET of 65 or 70mm.

The only way to know is either send the Kinesis serial #s to Lexani, perhaps they will look up the wheel specs for you(don't hold your breath though)

Or measure, here is a wheel

ET = backspace - 1/2(overall width)
