Help - 19" OZ Wheels Questions (C4S)

[roverelf]

I am looking at purchasing a set of mounted OZ Supeleggera wheels on e-bay. The owner got them as take-offs, and knows little about them, most importantly, offset. The link to the wheels are below. My question is, "will these properly fit my 2003 C4S?" If so, will they require a spacer? Apparently the ET is not cast into the wheel itself, so I am somewhat clueless at this point. OZ has not responded to my request for info to this point. Part numbers are:

Front - SR91570P25P0-R

Rear - SR92080P25P0-R

Any help/guidance would be greatly appreciated.....thanks.

As they say in their ad - "the rears will require spacers for C4S".

Yes, but they can't tell me what size spacer. That is why I posted....they can't even tell me where they got the information that the C4S will need spacers. Thanks for the reply.

That will depend on the wheel offset.

Email the seller and ask them for the wheel offsets -- then we can help.

Thanks. I have asked for the offset, and they do not know them. I even suggested looking for the ET marks in the casting, but they say there are none. I have even gone out to OZ Racing in Germany, but no reply to date. Hence my frustration. Do you know a "manual" method of determing offset? I don't profess to be a scientist........ Thanks again.

Thanks Loren. I'll pass that along and see if it will help determine offset.
