New Product: Rebuilt Clutch Intermediate Plates
I took note some time ago that a good used intermediate plate was becoming hard to find. If you did find one - it was often in worse shape than the one you were trying to replace...
Although they are still available new from Porsche, (at a premium price) we have begun rebuilding them. The goal here is just to provide an option for the 928 owner where they have no option at present other than to buy new.
Our rebuilt plate has an all new center section, made to the exact dimension of a new intermediate plate. I am very pleased with the quality of this item, and I am sure you will be too.
Note: there is one model for the 1980-83 928 and another for the 1984-1986 16v 928. I have 3 of the 80-83 models in stock now, and none of the 84-86 because I have been unable to find a core. If you need a 84-86 intermediate plate, you need to send yours in and we will rebuild it and send it back to you.
Testing: I'd like to get a couple of these out on to cars in the field. We don't have a car here that they fit - so I'm letting the first 2 intermediate plates out at a discounted price of $640 + core. You save $80. I just need a report back after you've installed it and driven it a while.
If you are interested, let me know.

how do you set the friction for the H adusters??
Looks nice.
I think i have a couple of old 84 intermediate places laying around too. one i think is realy nice, the other is not as pretty.
have you looked into making the pressure plates stiffer too for higher hp engines that dont want to go to a racing clutch??

Have the H tab adjusters been reworked?
simply replacing the I plate wont cure a loose H tab.
It may be better to replace the waved washers and rivets with a small aircraft grade bolt and nut setup this to anchor the Tabs in place

Here are some pics of what we're talking about. You can readjust this type of bolt setup, which incorporates wave washers, to maintain sufficient frictional resistance and correct adjustment, but you can't with the rivets.

The center plate is new, and machined from billet. That is to put back the sizing to stock spec, and of course, to correct grooved/gouged plates. The straps are new too.
The tee adjusters are original. We inspected them, but did not modify them.
FYI - if you have old intermediate plates and want to sell them, I posted that I wanted to buy them on this thread here: We are Buying 928 Parts on Page 3

I would very much like to get a 84-86 model intermediate rebuilt and on-hand before someone orders, so if you have that intermediate plate used, I'd sure like to buy it.

I'll pay $40 cash or give a $55 in-store credit for it. It just has to be all-there, and have a good ring gear on it. The friction surface can be scared and warped - no problem. I pay for shipping but the shipping has to be postal - cheapest way.

Both the GT2 and GT3 models can be driven on the street. I would say that the GT1 is the only "race-only" model, although I drive it on the street too... once you get used to a clutch, you can pretty much drive it anywhere. :-)

I think if your going to go to the trouble of rebuilding this part you should also modify the H tabs,
as they are a known weak point,
its not uncommon to have a brand new I plate with the adjusters that slip soon after installation and thus a dragging clutch.
Plus for what your charging this should be part of a rebuild IMHO
Selling these parts without the modded H tabs is sort of throwing away good money after bad
Since this is an easy thing to do why not incorporate it?
This would set your refurbished parts above the standard unit.

Not sure I understand, maybe you are not aware that we have been selling stiffer-than-stock pressure plates for years.

I did not perceive the H-tab modification as universally accepted, and did not know how well it would be received. I can still add the H-tab clamp mod if I become convinced it is durable.
How many times has this been tested? Who is running that mod now and can speak to how it is still functioning after 1,000 miles?
I understand the concept, and it seems to make good sense. Would like to hear from users of that mod to see what their results have been.

are these stock pressure plates that fit stock clutch systems, or your special aftermarket kit. i have had great sucess with just a stock pressure plate that has been modified to be stiffer , and stock clutch components. is this what you are talkng about???
We start with new OEM pressure plates, the assembly rivets are drilled out, the springs are changed (depending on the model) and the fulcrum points are moved (depending on the model) to keep from having excessive pedal pressures. There is more to it than that - but those are the main points.
No mods are necessary to the car. Uses the stock flywheel, release fork, throw-out bearing, guide tube, everything.

pretty much every I plate made is deficient in the H tabs attach points,
I dont think you need to do too much investigation as to if its a worthwhile upgrade, it will be!.
I had to replace 2 brand new I plates and finally wound up using the original one because of slipping H tabs
Since you have a picture of this modification it should be easy to duplicate
just make sure that all of the parts are the same weight so it wont throw off a vibration
