Hi guys. Where would I find the 'exact' part numbers for 928GTS wheels? I've checked several sites, all I could find where the sizes. With so many aftermarket C2 cups & 993 cups, it's almost impossible to distinguish true GTS wheels. I think the main difference is that the GTS had 7.5" wide fronts VS 7" on the 911's. I would love to find a site to cross reference. Any help pointing me the right direction is greatly appreciated!

GTS Cup I = 965 362 164 05 front 7.5x17 ET 65, , 965 362 168 00 rear 9x17 ET 55.

GTS Cup II = 993 362 124 05 front 7.5x17 ET 65, 993 362 128 00 rear 9x17 ET 55.

EDIT: TSB on the matter:

On genuine wheels, the part number can be found on the back of a spoke (11o'clock), the manufacture date on another spoke (9 o'clock), and the width and offset on the front next to the valve stem.

The first pic also shows the correct use of a kitchen bench top

You got something serious going on if you are propping wheels up with a FLIR case!

Not to mention a nearly full bottle of Maker's on standby!

So the Cup II's were made by Speedline but used the same design as the CupI's made by SM vs the Speedline design Cup I? Interesting.
