I think you are talking about the pressure plate and one from an early Porsche 911S will fit (+/- 1970 - 80). This is Aluminum with what appears to be a flame-sprayed steel/iron coating for the friction surface. I tried one several decades ago in my autocross Spider but had problems. After several months use a big "retaining spring" came loose and was rubbing on the inside of the bell housing. I also found the friction surface had worn down to the bare Aluminum. I'm sure this is a robust component otherwise Porsche would not have used it, so my autocross "launches" probably contributed to my situation. I went back to a normal Sachs HD pressure plate and use these to this day; along with a Tilton Aluminum flywheel that does a great job reducing rotating weight.

 

Yes, the pressure plate.
If I'm reading the 'Net correctly the all alloy version is no longer available new and NOS examples are in$anely expen$ive.
An aluminum cover and steel foot version is available but still over $500.00.
So a new aluminum flywheel is less expensive unless a bargain can be found.

 

The current oem style pressure plates from Sachs (and other companies) apparently come from the same factory in China and are prone to failure in modified, high-output Alfa engines. My racer buddies generally use old Sachs pressure plates in their race engines with no failures. There is apparently that big a difference between old, German made, pressure plates and the Chinese made pressure plates. Mine, from an 1986 spider, came from my friend Bob's stash of old pressure plates. Bob, who knows a lot about old Alfas, says that the old plates never wear out and don't explode in race engines. I'd contact APE and get one of theirs. Just make sure it was European made and not Chinese made.

 

Good information. I usually replace an older pressure plate under the "While you are in there" concept if the engine or tranny is out. How does one determine a German made pressure plate?

 

I have a few original pressure plates in my stacks of parts.
Will have a look for Sachs if it really matters.
I had hoped to shed a little more rotating weight but the $500 Kennedy units are a little rich for me.

 

The made in Germany pressure plates have either Made in Germany or Made in West Germany stamped into them.

 

One of my old ones has SCHWEINFURT engraved on it, whereas the other one, nothing.
I will call ZF.
Thank you Jim!
