[*]Did you match balance your new clutch assemblies?
Nope. They come balanced, and mine was vibration free.
[*]Did you remove the clutch assist spring to make it easier?
Nope. Actually it makes it 'harder' technically.
[*]Anyone using the McLeod adjustable master cylinder? What's your impression?
Nope. Not recommended with the Exedy. Using stock 01+.
[*]Did you do the "drill mod" to remove restrictions in your clutch hydraulic lines?
Nope.
[*]Did you install the slave bleeder line?
Yes.
[*]What difference did you notice with the aluminum flywheel? Does your engine spin up quicker?
It's a steel flywheel not aluminum. Spins up a bit faster, nothing major though.

Zero problems with mine...worked great at the track.

 

Hey guys - Glad to see you are having success with your clutches. The product has been proven year after year as the official clutch of the New Zealand V8 Supercar series, and I am happy to hear it is standing up to *real* American HP.

Additionally, our Australian sister company is working on a "Stage 1" / "Stage 2" clutch that will be offered with a flywheel for the more cost conscious consumer. We will let you know what R&D specs will be soon, but it will be a great entry-level clutch for a much lower price.

The most important thing I can stress is review the attached Spec sheet for our current clutch offerings, and chose the right clutch for your application. If you have questions, please feel free to call.

One word of warning - our clutch MUST be fitted with OEM hydraulics as it is designed in the shadow of the OEM clutch.

For you guys that have questions about the product, or need assistance I would like to put myself out there and help anyone that needs it. I know in the past Exedy has dropped the ball with customer service, but please call will any concerns.

Best clutch that we have ever used!!! These setups have held the biggest horsepower that we can throw at them. 382 supercharged, 427's, road race, drag race, auto-x, street. No chatter, no slipping, little pedal effort, WHAT MORE CAN YOU ASK FOR!!!

Thanks Exedy for making a great clutch,
Randy @ Doug Rippie Motorsports

 

Hehe, freudian slip?

Also, our Carbon Triples are now released for the Vettes and so far so good. We've had a lot of positive feedback from a few people that got early versions and they are holding the power... now to do something about shredding those tires...

I have been reading your various comments on the Exedy single and twin disc clutches for LS1 and LS6 applications. My company, Rockland Standard Gear is perhaps the largest vendor for these clutches of any of the master distributors on the Exedy line. We have sold several hundred of these clutches with only two failures, both of which turned out to be the result of installation errors. The product is a great product. We do not just sell these clutches, but we use them in professional race competition. I helped Exedy to develope these clutches in a Z06 Corvette that I drove in the Grand Am series for John Powell of Powell Motorsports. In this type of endurance racing, in which our shortest races were 3 hours and the longest the 24hrs of Daytona. Last year we campaigned the full season for the same team using the same single disc Exedy Hyper clutch in the Cadillac CTS-V. We have never had a clutch failure in any of these races, and that was a welcome relief for the multiple DNF's we had the factory supplied clutches.

One of the problems I see happening in the field is that many of the sources for this clutch have zero practical experience with the product. We build performance T56 transmissions for almost every team on the Grand American series, Speed World Challenge, SCCA T1 and T2 classes, and numerous NHRA competitors, and many of the well known Corvette, F Body, CTS-V, and GTO tuners. We don't just sell parts, we create performance packages that work as intended for the the customer's personalized details. You can buy the parts from many Exedy distributors, but if you wish the best prices with the best information and tech help from people who really care and can produce results, call me at 1-800-227-1523, or email me at mweinberg@rsgear.com. I will be out of town until Monday coming as I am driving a GTO in the Grand Am Rolex GT race in Mt. Tremblant, Canada. If the pro teams, and tuners like Mallett, Gigliotti, Lingenfelter, etc. use the product, why not use the expertise and product we can provide you?

Mike,

Very nice write up. It is good to hear that a well respected transmission specialty shop has such high regard for the Excedy clutch products. It would appear that there have been many with varied experience on this clutch...many good, some bad. I for one don't have the answers. So far, my Excedy Dual Disc has performed quite well, even in an environment (drag racing) where it appears not to be ideally suited. Perhaps the reliability of this clutch has much to do with both its installation and break-in. Of course, that is a conjecture on my part. The majority of complaints with the Excedy clutch (mostly dual disc version) have been by those who have very high HP and TQ cars and have tried to run the 1/4 mile with it and found it to hit the drivetrain "hard" resulting in a great deal of damage. One can argue this happens with other clutches, but the Excedy was "hyped" as the clutch to end all clutches for the drag crowd and many who bought it have had less than optimal success in this venue.

I have talked with my tuner and installer and we both agree that this clutch would be outstanding on a "twisties" track and your comments would appear to confirm this. With that said, it still doesn't help those who have seen this clutch fail (either directly or indirectly) in an application (drag racing) where many spent a large sum of money for it and have had issues.
