Boxster S 18" Turbo wheels - Genuine?

Hi,

I read somewhere(think it was Mark Bennett's Ultimate Owners Guide for Boxster/Cayman) that Porsche mark their alloys either side of the tyre valve with the rim width and offset. My 2002 Boxster S has 18" Turobo alloys but there are no such markings visible. I believe the alloys to be original but have only owned the car for a couple of months. The alloys have what look to be genuine Porsche centre caps in monochrome(black logo, rather than coloured). Does anyone know if my wheels may be genuine Porsche or an after market replica? Can I go by the markings next to the valve alone, or are there other Porsche alloys that do not necessarily have these markings? I'm a little concerned about doing high speeds on what might be after market rims of unknown quality. They certainly look like Porsche Turbo alloys! By the way, I believe the wheels were reconditioned by an OPC around 4 years ago according to a bill I have with the car.

Merry Xmas and a Happy New Year to All...
 
Part number should be on the rear of one of the spokes. I would say even if reconditioned it should still be there.
 
Thanks Nick_USA, checked today and there is a Porsche part number starting 993.xxx.yy.zz on the rear of one of the spokes. Had a bit of a drama with the wheel locating pin though, submitted a new post for this in case others have suffered the same.

Haven't seen your other post yet, but from past experience buy another and always use two.
 
Quite unusual for genuine Porsche wheels not to have the width/offsets marked each side of the tyre valve but your number on the spoke is 993 so I'd suggest asking on the 993 section of the forum with the full part number. Then you should hopefully find the dates between which these wheels were fitted and maybe the full info on them, offset/width etc.

Hope this is of help.

Thanks for buying the book! [:)]

I think I said usually marked either side... (There were a few wheel designs that did not follow this "convention", but given 2 otherwise identical looking wheels, the ones with the numbers would be the genuine ones)

Since the book was written, Porsche seem to be making ever more wheel designs *without* the markings each side of the valve, so removing the wheels would be the only method available to check.
