Jeaan knows his stuff

I just looked it up on a Porsche factory wheel list

other than that I dunno

Yeah, I guess the factory list would be correct! I was just curious!

Definitely magnesium centres on the 993 GT2. I was at a track day when a friend cracked one!

Probably not something that would have happened so easily with an RS aluminium centre.

Complete with "Radiographic Inspection Report for the Original Speedline Wheels", not something you tend to find with aluminium wheels!

Not necessarily

I believe Jean over what I posted, there are all sorts of typos in factory literature

The aluminum Speedlines will crack w/ time and use too, as will Fuchs and any other wheel you care to name

You may be right though the weights I found for the 9/11 GT2 Speedlines are 10.3/10.9kg compared to the aluminum 8/10 Speedlines 12.5/13.5kg

also I found where Jean mentions that the GT2 Speedlines on his car are mg.

Magnesium on the OEM Speedines on my 993 GT2. Part of the reason that a couple of years ago I had them checked, put on storage, and swapped w BBS E88s on the car. Extremely difficult to find these wheels, especially as a set.
