I bought a used "ACT Extreme SS" clutch but after getting it, it looks stockish. I really don't see any real difference between it and the old one. I did some searching through the "for sale" section to look at other pictures and it looks like, from the best i could tell, the others look the same. Now is there any identification marks on it or numbers? The only numbers i found were OE17 and something like 183000. The other one had different numbers for the first but same for the second too.

The yellow paint definetly isn't spray painted or anything like that.

 

I guess you will see if there is any difference when you try it out.

 

The ACT should be 40% more pressure , the diaphragm will be the differance . It could be the preload curve or the thickness .Take both plates to a clutch rebuilder and have the clamping force measured .

 

Alright thanks. Hopefully i'll find one around here.

 

^ that is a ACT pressure plate. Post a pic of the clutch disc and we can tell you more.

 

Here's the disk...


After doing some measuring, it does have a preload on it. I was just too tired last night to notice it.

 

Looks like a stock disk.

 

stock, see the four spring things? the REAL act one has 6...

 

Isn't that what the Street/strip clutch is supposed to be?

Every place i went to says it's mated with a stock disk. Even the ACT website shows a pic of a stock disk with 4 springs...

 

I believe so. I have the clutch disc which came with my ACT S/S kit laying out. I'll take a look when I get home but I do believe the ACT S/S kit is just an OEM clutch disc with a stronger PP.

 

You bought the ACT Extreme p/p with stock disc, I saw it in the FS section. They do indeed come with a stock disc. It looks like the real deal to me.

 

Yeah i couldn't pass up a deal like that. I was just getting paranoid.


Thanks guys for the help. God i love this forum........

 

I just purchased an S/S HD ACT clutch and the disk looks nothing like that. The center section looks more substantial. The build date is 8-10-2007 on the package, I thought it might just be a new disk design.

 

The disk that came with the kit.

Both stock and ACT disk

 

Attached are pics of my ACT S/S:

 

I e-mailed ACT to verify that it was the correct disk for the FD and it was. I sent out another today asking him if this was an improved disk, meaning not a version of the stock disk.

 

It was my understanding that they used the same disk, just different pressure plates on the disk.

 

Are you sure you have the S/S Clutch kit and not the "Extreme Clutch" kit? The Extreme Clutch kit comes with an upgraded clutch. The S/S is an OEM or "Street Disc" as they put it.

 

Yea, the part number (mz011) is the right p/p HD. I think the guy I ordered if from might have received an extreme disk, although from all of the sites I looked at, the p/n was the same between the two.

Edit: Just looked at the ACT site and it has three options for the disk. stock, modified, and performance.

 

Act only has the shows them having the stock disk available. Now does that mean they don't make more....no. There site also doesn't show them making a sprung hub 6 puck for the FD either.

Let us know what they tell you on whether or not it's an upgraded disk or not?

 

Good news from ACT.


It depends on whether or not the part you have is actually the 3000206.
In the past we the only disc that we offered for the RX7 was a stock
disc which was either a MZSD069 or 1000204 part number. Given your
description, this sounds like what you have. We then moved production of
the discs solely in-house which is when the 3000206 superceded the
1000204. As you noticed, the in-house disc is more substantial then the
stock units previously offered.

Thats cool that they upgraded there disks. Sucks that they did it after i got mine. At the time it was the same disk, only different pressure plates to go with it.
