What were 17'' 964 Cup Racing wheels made of?
I cannot find any reference to what the 8'' and 9.5'' Speedline 17 '' Cup 1 design wheels were made of!
Were they Magnesium or Alloy?
The 18'' 3 piece were clearly Alloy but I cannot find anything out about the 17'' one piece wheels.
Thanks

They must be rarer than the 7.5'' and 9'' originally fitted?
Porsche part numbers for the 8's and 9.5's as follows:
965 362 126 01 = 8''
965 362 128 05 = 9.5''
Original cost 5100 DM
How rare were these wheels?

I thought early cups used alloy and later cups used the RS mags. Later cups being based on RS chassis. Early cups on modded C2 chassis. I could easily have this wrong.

The wheels are 0.5'' wider than standard RS wheels, and I am told they are Motorsport items with AL/SI/MAG stamped on the inside of the rim.
I am guessing they are a lot rarer than the standard RS Mags hence its very difficult to get information on them.

Any of the "magnesium" wheels are definitely an alloy, combination of mg. and aluminum. Not surprised they do also have some silicon in the alloy (the "Si" is silicon, not -cone; one is a metallic compound, the other is something you use to seal your bathtub....).
I have been told the the 18" Speedline 3pc wheels on the Cups had mg. alloy centers. The street versions of the wheel (used on the 3.6T, 968TS, etc) had aluminum centers. This info came from a Euro Cup owner who cracked the centers on a couple of his original 18" wheels.

Oops..didnt spot my own typo on the 'Silicon'.
The wheels I am trying t find out about are the 17'' ones not the 18'' Split rims.
Thanks

964 wide-bodies (and WTLs) but not the turbos, were fitted with 17 inch 8 / 9.5 inch cup1 wheels as OEM. They look exactly like the cup 1 wheels (standard OEM fitting for 964) but are, of course, wider. They are definitely alloy. These are not "racing" wheels and one piece, not split rim Speedlines. Does this help?

The SM wheels were magnesium alloy, made in Germany and only standard on the Euro Carrera RS and were 7.5 inch wide front and 9 inch wide rear. Porsche claimed this magnesium construction saved 10.6 kg per set of 4 wheels.
The Carrerea Cup used the same part number, aluminum alloy, 8 inch wide wheel on the front axel that all 964 with the 17" Cup wheel option including the RS America used on the rear axel. These were made by Speedline of Italy.
The 9.5 inch rear wheels used on the Cup are of the same aluminum construction as the 8" wheels used on the front described above. These were also made by Speedline.
All the wheels described above look identical in a photograph of the car from the side.

No reference to the weight of these wheels though. I am thinking of selling my SM Mags that need a lot of work to be replaced with the wider Cup wheels...stronger and rarer?
