I've heard poor things about fidanza, but there is a positive review of the 3.2 on this site before you click on the forums. AMS will not even carry ACT because of all the problems associated with them like lock out, not to mention they're very hard on your transmission ( not my words, that is what AMS told me when I was purchasing a new clutch from them.) EXEDY HD cermetallic twin seems to be a winner. I think you REALLY need to go to a place that is used to putting in these clutches in our cars. They can be very trick so hopefully you live by one of the respected shops on the forums. As a last resort go to a respected dealer but you will be paying through the nose. A proper install is more important then getting the right clutch. I would also recommend getting SS clutch lines. My vote is for the exedy or the tilton twin cermatallic. GOOD LUCK!
TTP-Engineering installs over 100 clutches in the Evo 2003-2008 annually. Its one of the jobs we are notorious for.
You cannot throw any ol clutch into the Evo and expect it perform well. If you select the right clutch for the car, whether single, twin or triple, all of them will work flawlessly without lockouts.

Buschur Racing is a reputable dealer and installer. They stock Exedy, HKS, Fidanza, etc. I think if Buschur knew that a clutch was no good, they wouldn't sell it. Jarrod told me the Fidanza 3.2 was a good clutch, I think for a daily driver you wouldn't need anything more. A few track events and daily abuse and I think you would be fine.

Every vendor stocks and or sells certain lines of products. Take it into consideration when making your decision. Do not let vendor politics with manufacturers cloud you from selecting a great clutch.
We have personally seen Fidanza failures. One of which happened to be our ASE Certified tech's own personal car. In 600 miles the cerametallic disc crumbled to pieces and destroyed the fidanza flywheel in the process.

What makes the ACTs you sell not fall victim to lockout? I didn't have a problem with my ACT locking me out until I put my Red on. I don't know if its from having more power or what but the ACT gave me nothing but headaches at the shootout. I tried adjusting it but nothing helped. Anything over 7k and I had to wait almost a full second before I could get it into the next gear.

Evey clutch is going to have its ups and downs. I have heard great things about Exedy and then I have heard they fall apart. I heard ACT was a good street clutch and then that was continuously followed by negative lock out issues. I don't think any clutch for that matter is going to be completely perfect. I think its hard to believe how in 600 miles the clutch failed. I have been on my stock clutch and I'm around 52000 miles and it holds nicely.

I have the Fidanza 3.2 kevlar clutch and the Fidanza lightened flywheel and will never by anything besides Fidanza. This clutch feels stock but holds a good amount of power. IMO shelling $1600 + for any of the Exedy's is a waste of money. Price gouging at its finest.

well guys you are making it very tough. ttp has mad a strong argument for all of the clutches and i would like to hear about their act clutch that doesn't lockout and why it doesn't lock out. I also think that proper installation is key in any product and their are a lot of clutch failures because of installation error.

True. But before going with TTP, check around with other vendors (Buschur, AMS, etc) They have been in the game a long time and would definitely be able to take care of you.

With the proper singledisc unit, lockouts are a thing of the past.
With the EXEDY twin, plan on replacing the discs annually at $500 a pair + an average of $550 install and $50 in fluids.
Once the EXEDY twin overheats, the plates and discs warp and you experience lockouts even more often than the singlediscs.
Mellon has an ongoing thread regarding his continued problems with his EXEDY twin.
Our 2008 Evo X also is equipped with the TTP HD ACT unit and we can no-lift shift off redline in all gears.
We have installed, tuned with and driven Tilton twin hybrid, Tilton twin cerametallic, Tilton twin carbon, Exedy twin HD, Exedy twin SD, Cusco twindisc, ATS and Carbonetics twin and triplediscs, all ACT models, Fidanza singlediscs, clutchmasters single discs, EXEDY singlediscs. We have been there, done all that and our information comes from my own personal experience both on my own Evo's, as well as our hundreds of customers that employ us to install, tune and drive their own cars at the track.

ACT HDTTP as previously mentioned thoughout the forum. There are also a handful of positive reviews within the Service & Review Section of the forum.
Here are a few examples of those using our ACT HDTTP clutch.

The disc composite and pressure plate clamping force are both contributors to high rpm lockouts.
With the proper singledisc unit, lockouts are a thing of the past.
With the EXEDY twin, plan on replacing the discs annually at $500 a pair + an average of $550 install and $50 in fluids.

We have had problems w/ the RPS on a prev. customer car
We have 2 other Evo's that ran/run the Exedy twin and they both loved it and hold upwards of 400+ TQ (MD). The thing to remember once again is that the discs on this clutch are sprung as well allowing for a bit more forgiveness out of a DD.
Now i run the QM Twin w/ solid hubs and slow stop and go traffic an be a bit chattery.......but it does like to be slipped at a higher rpm so at the track it's all good
