Default Cup rims

I am planning on buying these C2 Cup rims. How can I tell if these are the genuine article or cheap imitations?

Default C2 cup rims

Sorry, forgot to attach the picture.

How can I tell if these rims are the genuine C2 cup rims and not cheap immitations? The rims are now on a 3.2 Carrera.

If it has a 965 part number, it is the real deal.

Easy way to tell if they are factory rims is if there are raised numbers on either side of the valve stem giving the rim width and et (offset) . If you can look at the back side of the wheel, you'll know for sure as was mentioned with a 965 prefix on the part no.

Don't buy them if the front is a 6" wheel. You want a 7" for a 225 tire anyways.

Here are some pics of a stock rear Cup 2 (that I've just had refinished to better than factory inside and out) .. you can see the width and offset marks near the valve hole, and the P/N inside.

Standard Cup 2's are 7.5" ET 65 front and 9"ET 55 rear.

Rear P/N is 993 362 128 00 and front P/N is 993 362 124 05.

The Cup 1's have P/N rear of 965 362 168 00 and front P/N of 965 362 164 05.

It's a bit difficult to see in that photo, but I can't see the width and offset raised cast marks near the valve hole so I think it's likely they're replicas.

Don't buy any wheels unless you have a picture of the front and the rear of each one, that clearly shows part numbers and cast marks near the valve hole (which genuine wheels have) ... so you can identify what's being offered.

You also need to know, with any secondhand wheel, that you're buying wheels that haven't been damaged and then repaired.

Sorry to go OT on the reply too Heinrich ... the guy that did them for me here in Tasmania has been doing wheels for 30+ years and works magic on them. He does lots of wheels on brand new luxury cars for owners who are not happy with the factory finish, and work on competition custom wheels, etc etc.
It'll almost be a pity to put them on the car.
