I don't think the dyno comment was directed at you.

Plus one on the ball cup my 82/Gts did the same thing it rattled and once replaced was quite! Easy quick fix
Might as well ask the next question now.

How do I get in touch with Mark ?

You need to remove the clutch slave and the air filter housing, then from the top you should be able to slide the clutch arm off the ball stud. This will allow you to slip on a new bushing. Replace the arm and re-install the slave cyclinder and air filter. Should be able to complete the entire job in less than one hour including a beer.
BTW Thank You

My GTS sounded kinda like it was pinging with a little bit of rattle when the clutch arm ball cup started disintegrating.

There are 3 most likely possible causes for your issue:

- The bushing on top of the clutch arm is disintegrating or missing
- The guide tube bolts are getting loose and are hitting the coupler
- The release bearing is dying

Oh, and as has been already mentioned, you do not have to remove/disassemble the clutch to replace the arm bushing. You may have to manually pull the arm and install pressure plate shims though.

I agree, in fact my 89GT will easily shift with this method, WITHOUT USING THE CLUTCH, as long as you match engine and tranny speed. Using fingertips allows the synchro rings to do their job and when the are ready, You can feel it and the shifter drops into gear.

I showed this to a guy who didn't believe in the Porsche tranny one day on a ride through the back roads. The only time I used the clutch was to start off in first gear, for about a half an hour ride of chifting repeatedly.

"Finess".......... a little does not hurt.

Yes. Some are able to do it without touching the pressure plate, others have to release the clutch and shim the plate to have enough room to get the lever off the ball.
