clutch replacement (to use stock flywheel???)
Honestly, the HDSS should hold just fine for the power you are talking about making.

Check out my review of the ACT HDSS and the Xact flywheel...

I think you'll be happy with this setup!
One thing you should figure out.. if you are going to crack open your trans anyways to install a new clutch, might as well get a new flywheel either stock or aftermarket. I've seen some new oem flywheels on *gasp* Ebay and it didn't cost too much, maybe < $100 more than having your used flywheel resurfaced.
Good luck!

Really safety is not much of an issue on the EVO since it is not a grey iron casting like most flywheels. Usually the issue is finding a competent automotive machine shop to do the work right, and a dealership is not willing to risk it. They would rather replace the part with a new one.
In the case of grey iron flywheels, cracks can form when they get overheated and then the cracks grow so there is an increased chance of catastrphic failure. That is a real safety issue because it is like a bomb going off! Basically if there are any visible cracks on a grey iron flywheel (or really any flywheel) it should go in the trash. A grey iron flywheel has less tendancy to warp and more tendancy to crack than a ductile iron or steel flywheel. Since the stock EVO flywheel is not grey iron it is much stronger and more prone to warp when it is overheated rather than crack.

I am trying to decide on my driving habits if I should go with the
ACT HD
or exedy twin
Still doing research and calling around.
I was told the HD put more stress on the rest of the car drivetrain/transmission than the exedy twin SD.
I was also told that the exedy twin would outlast the act HD simply because they work differently.
However, the price difference is tremendous and that extra 1000$ would buy me a evo green
so i'm trying to play this smart and get the best thing for me considering I don't wanna replace a clutch for at least 2 years or more. I have owned a lot of cars and I am surprised I only got 13K out of my stocker. Guess all those riding the clutch a little launches took me by storm.

The EXEDY SD is not any easier on the trans than the ACT.
Someone just wants to sell you something.
The MM022SD is an insufficient model for the Evo in clamping force and only the MM022HD should be considered.
Honestly way too much thought is going into this...
You think about power goals.
You think about primary uses of the car.
You pick the proper clutch.

I think my ACT HD organic disc is great. It held 484 whp on our dyno dynamics which is about 550 whp on a DJ. The pedal pressure is just slightly stiffer than stock, but still holds massive amounts of power while being easy to modulate.
It is the clutch I recommend to most of my customers when they call. Another added benefit is that it is very affordable.

I want to say you are right, but the fact is "he isn't selling me the clutch" he is just installing it, so i'm sure he doesn't care one way or the other what I go with.
You would think that the grab and go clutches (high clamping forces) would be more strain on the drivetrain components than a lighter clamping force twin disc.
You might say its too much thought, but when it comes to something like a clutch for "my" car I am going to take all the time I need.
I haven't ruled either out yet.

#2 The EXEDY twin consists of cerametallic discs which engage much faster than the organic material of the ACT street disc.
Which makes the EXEDY HARDER ON YOUR DRIVELINE.

#1 The SD Exedy has proven time and time again to be insufficient for the Evo and ends up needing new discs within about a year at $500 +$550-$1000 labor.

You do installs right? What are the amounts (%) of the clutches you do? Brand, model?
Also, what do you customers say about these particular models, brands?
