Authenticating D90s etc

[Li Moo Bai]

Have an option to buy some very nice recently refurbed D90s for my 944 and was wondering how the pukka porsche wheels can be distinguished from imitations?

Thanks.

I really don't think you have to worry about fake d90's, but the real ones have the size next to th valves and a porsche part no on the back.

Real ones will have the size and offset stamped either side of the valve (I think) and a Porsche part number in the middle in side - something starting with 964 or 944 I should think.

Didn't even know that there was such a thing as a fake D90 ...

You will occasionally find a 928 stamped one! I have one and it is vewwwy wide

Fake D90's - mmmmm - it didn't occer to me before I replied that I had never, ever, seen one anyway. But you might end up with the wrong offset I suppose, or some of those luvverly 944 turbo forged wheels that seem to last about a fortnight before they start to corrode again.

A 928 D90? I thought that the 928 wheels were different to the D90 - and looked different from the front?

Did the turbo forged alloys rust then? Didn't know that. Glad I didn't buy a set a while ago then ....

The forged alloys dont rust but they corrode badly - mainly through contact with brake dust. I had a set recondioned at huge expense to get all the pitting out, then powder coated, put on loads of polish and protector but a few months use and accumulated dust and s**t saw them start to go again.

The 928 guys will know, but I think it came off one model for a very short space of time, forget how big it is but it is 1" wider than a standard 964 rear. Have been looking for a matching one for about 4 years! Now car is up for sale I might as well give it to the new owner, or keep it as a coffee table!
