very common, and don't waste you time trying to get the dealership to warranty this, then you will be stuck paying too much for a clutch and getting the same stocker....

 

My clutch went at 5,200 and my wifes went at 42,000. It all depends on your driving habits. The design isn't that great from Daikin for this cars main purposes. We have one of the hottest running setups out there and the design and materials do not allow "spirited driving" for a prolonged period of time.
On the pressure plate surface there are 3 tabs/fingers that act as a limiter when engaging the flywheel as your disc engages. Once those fingers wear down, the disc has a hard time engaging, slipping etc... etc... I'm not sure why they did that, but it may just serve as an indicator for service techs.

 

LOL!

 

Mine is slipping now big time even in 2nd gear. I'm at 7k on my stocker, i'm not suprirsed because i've abused the thing, one too many times slipping it on a launch. So i'm getting a new one fairly soon.

I'm thinking I'm gonna go with the ACT HD

 

I did not like my ACT HDSS, fwiw.

 

There are alot of options out there now....some new some old. Its all about getting only what you need... do your homework...and search is king for clutches...sometimes

 

I'm on my second ACT HDSS and FYI like it just fine... I find that the pedal feel isn't too bad and I've never had any of the lockout issues (on either of the ACTs) that some experience.. I've never driven a car with a Exedy though so I can't really give you a comparison..

 

Yea i'm not sure, I don't need a twin plate, and the only option for a single I think is the ACT, the exedy organic and the Exedy Cerametallic.

 

lol..yeah i didnt bother searching. Apologizes for in a sense recreating another thread that someone has already answered. Warrtalon being that you have the exedy hd clutch, it cost a pretty penny compared to your ACT clutches. What makes it so much better. I wouldnt mind spending the extra amount although i cant imagine a clutch being almost 1,000 dollars better?

 

If you need a flywheel too, Fidanza also cam out with a full line of clutches. I have one on my car a cerametallic and my wife has their kevlar disc. No problems thusfar and my left leg is not abnormally larger than the right.

 

With my first ACT clutch I mated it to a aluminum Fidanza flywheel.. I did slightly notice that the car would free rev a tad quicker making it easier for me to rev match, BUT on my current ACT clutch I decided to go with a resurfaced stocker.. Honestly, for the difference in price I probably couldn't justify spending the 3xx dollars for another Fidanza as there isn't that much of a difference IMO..

 

Let's bring the prices back to reality first. An Exedy Twin HD will cost you around $1350, and it INCLUDES their lightweight chromoly flywheel. The ACT HDSS will cost you $500 and does NOT include a flywheel. An aftermarket lightweight flywheel or new stock flywheel will cost you $200-300, so tack that on, and we're talking more like $750 vs $1350. Yes, an Exedy Twin HD cerametallic is definitely worth that extra $600, because it will shift better, launch better, hold more power, not have any lockout issues, last longer, withstand more abuse, and have a much lighter pedal feel.

I don't have that clutch, though. I have used the ACT HDSS and did not like it at all for multiple reasons. It wore out at 9500 miles, but with a lot of racing, so don't think that it just randomly gave out at 9500 miles - I did rock its world, but it couldn't handle it for long. I then was sent the 4-puck cerametallic SINGLE DISK from EXedy to try, and I loved it. It is not for the faint of heart, though, because it's a puck-style that is harsh for initial engagement, but since it's still sprung, it's not bad for driving/shifting once you get moving. I daily drove it with ease even in traffic, and I raced the dog mess out of it with no lockout issues EVER. I was able to powershift every gear with utter ease and without thinking twice, whereas the ACT always had me wondering if/when I'd get locked out. My ET vs MPH ratios were much better with the Exedy than the ACT. That 4-puck is $950 or so, and the price includes a lightweight chromoly flywheel just like the Twin.

Exedy then sent me their Twin Carbon, which is what I use now. It's the most amazing clutch I've ever felt, because it drives as easy and smoothly as the stocker for daily driving, but then it can take all my abuse for racing, too. I haven't been able to put it through a full racing season yet, but I will be doing that beginning in March. Carbon clutches behave differently and are known to not last as long, since you have to slip them to heat them up so that they operate at full capacity, but I am just testing it for them to see how it does on the Evo. After this one, I plan to just go with the regular Exedy Twin HD cerametallic for long-term use unless they have more they want me to test. The Twin HD is proven and is the clutch of choice for most Evos.

 

thank you. thats exactly what i needed to hear

im curious to know where did you find it for about 1,300. i cant find any cheaper than 1,600

 

I thought this horse was already beat enough. Warrtalon made high rpm lockout famous with a misleading thread that claims ACT will cause unpreventable lockout that other clutches won't. This was in spite of numberous people reporting experiences to the contrary. I have seen lockout with many other clutches, including the Exedy twin cerametallic and twin carbon and the problem is really simple to explain. It either happens from not having the clutch adjusted right in the first place or it is caused by overheated parts that warp and therefore the clutch doesn't release as it should. This is precisely what happened to your ACT. Since the Exedy carbon rides against steel, the steel plates are prone to warp just like any other clutch if it gets too hot.

Now if you want to avoid lockout, no matter how much abuse you give it, consider the Tilton Carbon/carbon. In that case the plates will never warp since it is true carbon on carbon, but it will break the bank.

Here is a poll on clutches to consider. Apparently there are some that like our clutch, in spite of the rumors. I think the count is up to like 350 or something:

As much as I would love to pick up a Exedy Twin HD right now, I can't afford it at the moment, i could pick one up in prob two months, but i'm afraid the way my clutch is now, its not going to last that long. And i'm going to be SOL without a car to drive to work.

So I'm kind of in a bind at the moment. What do you guys think, the exedy organic or the ACT HD? This is my daily driver, i drive it stop and go traffic most of the day usually around town.
