"Spec" clutches?

prostreetdsmx1, I'm getting ready to order one from your site then and would like to know what is the difference from the 6puc and 4puc? Does anyone have a preference? My profile is pretty much up to date except I've added my injectors finally so it's getting to be time to get a engine rebuild and a clutch/flywheel combo. Any suggestions?
 
I could be wrong on this one, but I think that the 4 puck is the old model and you can only get the 6 puck now. I got the 6 puck and it does grab quick, but it is very easy to get use to. I should also note that the stage 3 has a very lite pedal feel. So far I am very happy with it.

You are right the 4 puck is the original design. WE still can get it that way so we still offer if but don't recommend it. The 6 puck is the way to go. It grabs really well and also holds on for dear life. Great way to go.
 
I originally had a Spec Stage 2 kevlar clutch that worked well until it was contaminated with oil. I went ahead and upgraded to a Stage 3 6-puck, and its almost as easy to drive as the 2 was, but it definately grabs much harder. There's also an optional cabron/kevlar weave Stage 3 disc which isn't as harsh as the carbon-metallic standard Stage 3, but has approximately the same torque holding capability.
 
Titan Motorsports is selling Spec clutches (Stage I and Stage II) for under $300. Has anyone dealt with these guys?

damn folks, can i make a dollar. LOL. If you see a better price out there let us know and we'll do our best to take care of you. Also keep in mind our prices are SHIPPED and we should get points for being supporting sponsors of our beloved board. :p

:dsm:
 
Prostreet, You are my new favorite vendor. As soon as I get some more money I am going to send some your way.
 
Can you tell me if a Spec Stage II clutch will put as much stress on the crank/tranny as an ACT2600? How does it compare with that and also pedal pressure change over stock?

Thanks!

I don't know if the stage II will put more "stress" on the drivetrain. I can tell you that the engagement at engage/disenage is smoother which is easier on it and the pedal pressure is significantly less than what you would get from a 2600. This coming from a guy that just took the 2600 out of the GSX i just bought that had under 10k on it. ;)

Pedal Pressure is a tiny bit more than stock.
 
I just installed a Spec Stage II clutch last week. Stage II and stage III use the same pressure plate, but stage II uses a segmented kevlar disk and stage III uses a sprung puck disk. The kevlar disk design was very unique. The best way to describe it is a combination of street disk and puck disk. The surface area is one solid piece, but 6 kevlar friction pads are raised so that the disk only touches the flywheel and pressure plate on their 6 friction pads. It's hard to explain, so I'll try to find a pic. I am assuming the areas of the disk that do not touch the flywheel or PP are for a cooling affect, much like a puck disk.

But anyways, Titan Motorsports sold it to me for $300 shipped to my door, which was an awsome price. Titan are big in the Supra community and were very good to deal with. Peddle pressure is very comparable to the ACT 2100 I had in my previous DSM. I am very happy with it so far. Very smooth egagement and grip when you need it. I have nothing against ACT, but after a lot of research, I wanted to try this clutch. And I wasn't quite sure my high milage tranny could take the clamping power of a 2600. I think Spec will be one of the new and upcoming manufactures in the DSM community.

I will be sure to keep you guys updated as I put some real track time on this clutch setup.
 
Excellent write-up. Did you get an OEM TOB from Titan or did you have to get one from Satan?
 
I was waiting to finish break in on my clutch before posting.

I had an ACT2600 that I burned up. I was going to just get another ACT2600 but I decided to try out the SPEC stage 3 6 puck clutch. I so far like this clutch alot. It has a little more pedal pressure than stock but not as much as the 2600. The clutch holds really good and can be slipped for some nice launches. I also have not had any chatter at all since driving the clutch. It took a little getting use to since I switched from the 2600 but all in all its a good clutch. As far as the comment on the throw out bearing not fitting it does fit it just takes some fiddeling with to get the wire clamp on the fork since its a super tight fit. I can recommend this clutch to anyone who is looking to an alternative to the ACT 2600. :thumb:
 
Hmmm, I was under the impression that the stage 2 was like the 2600, but the 2600 is rated right around 400 ft/lbs which seems very close to the stage 3. I was hoping the stage 3 was stronger than that because I need a clutch that can handle quite a bit more torque Does "spec" make a stronger clutch?

On the other hand I saw that someone posted about using the stage 3 clutch in their 10 second car. So I am a little confused about how much power it can actually handle. What are you high HP guys using for a clutch?

Thanks
 
the best i have been told by a customer was going 11.2 on a Stage3. I would rate the stage 3 stronger than a 2600 and definately lasts longer. specially with the 2600s that have been falling apart lately.

You can always go with a solid iron unsprung disc Stage 5 OMG :nono:
 
Yeah, I looked on their site and saw the stage 4 and 5. What is the difference between stage 3 and stage 4 in terms of pedal pressure? How much power can the stage 4 handle. Also have you ever used the stage 5? Is it streetable, is the pedal super stiff?

Thanks
