On a new clutch about how high is the friction plate over the rivets? I have about 1-2mm,(not original clutch), which I'm hoping to last me a number of years for light street driving.

1-2 mm is a few shifts away from a trip to the machine shop to resurface your flywheel.
Time for a NEW clutch!

It seems hard to believe that you wear 1 mm off the clutch with every shift.....
It may be thin, or it may not be.
I personally think that if he has the clutch apart (and is measuring 1-2 mm directly) he may as well replace things "while you are in there". And a clutch is only $400-500, right?
Sometimes I think we get a bit hysterical about "what could happen" on this board... Maybe I'll start a new thread on that!

Hello Rocky; For myself an afternoon of track time at Laguna Seca is worth 1mm of clutch wear!!!
I personally value my time.
If "I" had a ZF removed from the engine to be able to measure 1-2mm LEFT between the clutch surface & the rivets, there would be NO reinstalling that clutch!!!

I get the message. There's just no information out there stating the original thickness, and rate of wear. The Centerforce friction plate is only $88.00, so it's really not something to sweat.
Exactly, although many do buy a complete clutch kit, it really isn't necessary to replace the diaphragm, just the friction disc will do if you are on a budget.

The lining of a clutch disc is like brake pads. It is designed to wear.
Everything is involved in the rate but the lining itself is not the issue with a Centerforce.
It is the silly things like the fingers on the pressure plate that wear disproportionately in comparison to others.
The problem with Centerforce is that it has become a two bit company because the original concept was not adhered too.
It has been sold several times and components are manufactured "off shore" and are supervised by "sales oriented" managers rather than actually pay an engineer who understands and more importantly CARES about the integrity of the product.
Use your Centerforce and when it is due for a new unit be advised to go elsewhere.
The Chinese and Vietnamese who make this thing now just are happy to have a job and just do what they are told to do.
That has absolutely no basis upon the quality of their product.
Rather than have the diaphragm fingers blackened from heat treating like they are supposed to be, they just spray them with black paint.
Not quite the same thing and the product is now just a mere shadow of what it was.

I would also note it's hard to get the P/N for just the clutch disk from Centerforce.
After a whole bunch of detective work, I found it, but they wouldn't sell it to me direct. I finally had to buy through an authorized Centerforce dealer. It was as if they wanted me to buy the whole assembly for the Pantera. Maybe not too surprising.

Believe me, I get the whole quality thing. Fortunately, this car is more show than go, so it'll be okay.
Here's a link for just the plate for a -1 transmission:

for what it is worth
I read through the service manual and bulitens and surprised not to find any mention of replacement thickness.
google for different applications seemed to be consistant in a "surface to rivet" minimun of 0.3mm

Also note- that plate number is for a dash-1 (or a dash-1.5) ZF, which uses a different 1-1/8-10 spline size than the much more common dash-2 ZF, which uses a 1-1/16"-10 spline. It may be the 1-1/8"-10 disc will be available for quite some time as it's a Chevy transmission spline size.
The full thickness of a center disc is just at .370 to .375" depending on who's it is.
