Thanks!
Since 964 Cups were NB, then you can use the 9.5" ET68's in the back with the 21mm spacer (giving you 47), but you will have to roll the fenders.
Additional info is here:

but anywhoo.... Motorsports only called out these 2 wheels for the 964 cup cars. No 47mm in 17" for the 964 or the 993
That answers why I have only heard/read about 9.5 47 offset here, but have never seen one (from Porsche).

I'd be happy with just 2 sets.
I found mine with the car pictured to the left, which I bought from the original owner. They were about $6k per wheel.......

OK, I dug out my parts catalog for the Cup cars. Here is the scoop.

The 3 piece Speedline wheels used for the 92-93 Cup season:

965.362.136.00= 8X !8 offset 52 mm front wheel (same part number as 3.6 Turbo front wheel)

965.362.138.05= 9.5 X 18 offset 47 mm rear wheel (not used on any other car I know of)

The one piece cast Speedline wheel used before the '92 Cup season:

965.362.126.00= 8 X 17 offset 52 front wheel (same as rear wheel RSA or 17" wheel option 964)

965.362.128.05= 9.5 X 17 offser 68 mm rear wheel (also used as upgrade option on rear of 3.3 Turbo and 928, needs 19 mm spacer and long studs)

I guess that is why I have seen them on 928GTS models over the years....likely all brought to the US very heavily optioned.

Hi,

I have those 9,5" Rims on my 964RS.
Look at my Avatar and the added pics.

I use the 21mm spacers. That´s important, ´cause the tires must have enough
space to the axle control arms.
It´s possible to use 25mm spacers.

Cheers

Sparxx
