I'm pretty sure you are looking at 2K parts and labor.

Does any one know the correct FORD PN for the CSC to be used in a 2007 install of the SPEC Twin Disk SS trim clutch?  There seems to be two part numbers out there..and Van at Raven is off setting records at the TX Mile this weekend.... Was hoping to order today, so parts are waiting on me when I get home in a few days..

Thanks

Spec has a terrible dealer program, so alot of dealers do not push the Spec. I can't change that, but the Twin SS flat out works great.

Those of you that have met me, or know me, know I do not ever push a product that I will not use in my own cars. Take that for what it is worth. I really could care less for $51.  The Spec works, and works very, very well. End of story....I don't care if you buy it from me or a vendor that buys 100 at a time, you will not regret the purchase. Just make sure it is a unit after Nov of 2010. The McLeod unit is fine, but does chatter alot. Dealer program is great, so many push them, but I do not feel it is as good of a clutch as far as pedal effort or longevity. I have replaced them in less than 1K miles for many.  If you want a clutch that will handle what you put to it, get the Spec Twin SS.

Hi Alex,

Rob pointed me in this direction....


I'm going to have this Spec

clutch replacement done on my 2007 SS (725HP) shortly either at Sean Hyland near Toronto or Evolution in Pa.

Do you have a part number for the Spec clutch for my application?  I don't want to make any mistakes at this point.  Clutch driving me nuts.

Thx much...and i will replace the Ford parts as well as you recommended.

Regards,


Mark


Anyone had Hyand or Evo handle their clutch replacement with a Spec or other product that has worked out well?

[E.Marquez]

I just bought all of this in the last 24 hours...


The SPEC Super Twin -SS Trim is SKU: SFG5SST
Van at Revan Racing has a great price, as does Leathal, Revolution, and others.

OEM parts replaced everytime a clutch is done...

Best prices on these two needed items are from Tusley Ford:
Concentric release bearing (In Ford speak, Slave cylinder, in common terms release bearing) FORD OEM PN: 4R3Z-7A508-AA $172.47.
Transmission imput shaft Flywheel bearing FORD OEM PN: M-7600-A $7.43

I'm not having a problem with my car, but I was wondering what you guys think of the Spec SS-Trim Twin Disc Clutch Kit and Flywheel. Is it smooth and quiet ? If you have this unit in your car, please tell me how you like it. Your comments will be very helpful to others needing to get a new clutch.

I see the unit goes for $1,329. I assume you guys had the CSC and pilot bearing replaced when you had the job done and the tranny splines lubed with the Ford blue lube as well.

Mine would be much different then yours

Though I can only speak to the product, as Ive never had an issue with the product to need to deal with the company.. Just order SPEC clutch 4 and 5 for our latest installs, 2005 S197 GT Mustang and 2007 GT500...

Sucks you had a bad expererince , but as I see people smoke all brands of clucths, due to shooddy install, partial parts replacment, and poor driving habits.. a few bad experiences com[paired to the many times more good ones.. as well as my own have sold me on the brand.

Wow, price from Tousley for the slave cylinder has gone up!!  I purchased that part from them back on May 26, 2009 and paid $139.74 plus freight.  Almost 10% increase each year  LOL

[Reaper69ZA]

What are the dimensions of the clutch kit? Height, width, length? (In the packaging)

I am trying to order it and get international delivery but the shipping rates are killing me... Hopefully, when I have the dimensions, I can source cheaper couriers.

Also, can someone confirm the weight of it? Approx. 20kg?

Awaiting a quick response.

Thanks...

We've got the Spec SuperTwin P-trim in our two super snakes, they are noisey as hell.  You get drive-line noises and serious vibrations through the entire car at lower rpm in higher gears and they rattle/chatter sometimes when you are trying to slip the cluch in tight places like car parks.  Getting the car moving off the lights without dumping the clutch or chirping the wheels isn't easy especially on a hill.

They do hold the power, there is no doubt about that.  The loss of drivability though almost ruins an otherwise fantastic vehicle.  Anyone who tells you "they drive like stock" is full of crap, I presume the S model maybe more user friendly but the P-trim is the one that was recommended for our 800hp super snakes.  These came highly recommended and are very disappointing.

Having driven a super snake last weekend with the stock clutch I'm thinking about pulling the spec out.  Changing the stock clutch every 10,000 miles doesn't seem so bad.

On the stock clutch I could drive in 6th gear at 60km/ph without any noise.  If I run 6th even at 100km/ph with the Spec clutch the drive-line sounds like its going to explode.

Spec support was hopeless as these apparantly are "normal" traits.

I have the P trim in my car and not having near the problems you are. I don't slip the clutch , does shutter if trying slip it to much.  Drives good at 60 in sixth gear but I down shift to 5th for hills. not much noise, happy with mine

[gtt500]

I also have the Spec P-trim,not the best in traffic or on hills but no noises or vibrations.

I went with the 2010 stock set up. It is such a pleasure to drive. It makes driving the car 10 times better.  See link for cost:

I run the S Trim and have zero issues like reported above.

Not a Super Snake power level, just a healthy 634 or so at the wheels...... BUt I for one am very happy with the clutch.

For those that are eligible for the most current TSB that uses the 2010+ system, it is more than adequate for stock or mildly modified applications with less pedal effort and no noise. If you modify your car past 550 RWHP, you will destroy it sooner than later....been there done that. I deal with street cars, road race cars, and drag cars every day and have many that have complained that the 2010 clutch has held up worse than the Pre TSB clutch and the Post TSB clutch. My own 2010 clutch lasted less than 100 miles when I upgraded to the Kenne Bell 3.6LC. The clutch was slipping and I couldn't even tell, the Dyno did. I went from 666 RWHP to 763 RWHP with just the addition of the SPEC Twin SS. 7K miles later, no issues. I have people with over 30K miles with this Twin SS system with no issues.  Remember everyone,. there are positives and negatives to each and every clutch system out there and there are many dealers that will try and talk you into the clutch they make the most money off. SPEC has a pretty poor dealer program, so many dealers don't push them. There is a very little profit margin on a very good clutch system, so many dealers do not push them. Another thing is that there are dealers that sell SPEC clutches that have been sitting on a shelf for a long time...the early versions are not as good smoothness wise as the ones made from November of last year.  Been there done that too. The ones that sound too good to be true, usually are.  ALWAYS replace the CSC with a new FORD unit too...Why?? Because the CSC wears on the front face to the pressure plate. I have people with 300 miles on their car, insisting to use their 300 mile CSC, and I won't do it, the CSC will fail before the clutch because of the wear pattern. ALWAYS use a new Ford CSC!! ALWAYS use the blue input shaft lube!! Do your home work and determine what you want to use your car for and figure out what is best for your own application before spending the money on a clutch system for your car. The right decision will give you years of enjoyment out of your car with out the feeling in the back of your head "what if". Too many people have made the wrong choice, sometimes several times over, and it is not worth the effort time or money wise.

I had the Spec Twin SS installed in June.  My car is 642 rwhp so its healthy but not a monster.  I have put about 500 miles on the new clutch and I hate it.  Drivability is miserable on the street. I am sure it is great on the track but the chatter that occurs upon engagement ruins the experience of driving the car.  I was told to drive it and the surfaces would mate.  NOT HAPPENING.  I am going to opt to dump the Spec and go back to the Ford upgrade unit.  I would rather replace the ford clutch every 15,000 miles than shake  my car apart at every light.  If you are considering a new clutch I highly recommend not considering the Spec unit.

Horrible to hear, seems to be a complaint we see about most any brand aftermarket clutch installed.

The only clutch consistently reviewed as pleasant to drive is the OEM 2010 clutch.

I have no way of understanding why my SPEC S trim clutch and the other two I installed are working well for us, and others find it a chattering PIA on their car. But there are just too many reports to ignore.

I'd still recommend it, but suggest that it only be installed by a shop that has a proven track record with SPEC.

Life to short to drive an ugly car, or one that even feels ugly.

Best of luck with your 2010 OEM install.
