I have bought an original used Porsche CS steering wheel, but the hub that came with it is missing the splined bottom part that goes over the steering column. I am trying to decide if I can just buy the missing part or if I have to get a new hub altogether. In either case, what is the correct part/hub I need? Photo is my how my hub looks like currently.

The 3 small threaded holes you see are where I removed the plastic/horn ring brass slider that also returns the turn signal. The hub seems to be bolted at the large 3 holes in yours, you can see the rear of the bolts at the larger holes IIRC these wheels/hubs etc.. were made by Atiwe for P so perhaps you can find some Atiwe parts/hubs that will solve for you.

Pic from inside the hub, you can see the allen head bolts that hold the alloy hub.

You need an Atiwe 1729x hub, you can usually find them for sale in various places.

Once you get the right hub you'll need a resistor or some such to turn off your airbag light, too. And a horn contact switch, part no 928-652-104-00. The install itself is super easy and the wheel feels / looks great!

[edit: you're in Australia, so maybe no airbag to worry about?]

Thanks for all the replies.. I believe its a Atiwe 1729x hub I have already, just without the splined part. But if its not possible to get that splined part separately I might just have to get a new one. I already have a resistor for the airbag, but I also need a horn ring?

You will not be able to buy just the splined part unless someone just has one laying around. It’s only sold as a complete hub.
