Oh, no doubt the price is high... You are prolly right in that most can't afford it either. I could get one of those but it would equal in cost the installation of cams & intercooler.. Tough choice
Now, if the budget is more limited and I'm willing to compromise on some aspect, which are the other choices that make sense?

I'd list these priorities in order of importance:

1. Reliability/durability for 400 hp - 400 lb/f tq.
2. driveability
3. price
4. availability

Given those, which clutch makes the most sense? I mean including the metal ceramic or fiber clutches including those that use the stock flywheel......

 

I'm not knocking what appears to be the best clutch out there right now... hands down... I'm just pointing out that 90% of the Evo owners are not going to buy them because they can't, or won't due to the extraordinary price. They will probably only afford something along the lines of the HKS twin discs on the top end... esp with more and more options coming out every day that will hold 400+hp (or better yet ft lbs of torque). Hell, the ACT PP with OE disc will most likely sell more units than any of them due to it being able to hold over 400 ft lbs for the price (not to mention their rep with the DSM community)... remembering that 80 to 90% of Evos will never see 400 ft lbs...

 

I'd have to agree also. No need for a triple clutch. Plus with a triple enagement will be slower. Plus cost is much higher and there are many killer double disc clutches made for the EVO that will handle the amount of power and torque for a street car. ATS makes great products but just a cause of over kill. A Ogura twin or HKS twin will fill the bill just fine. My friend had a triple in his R32 and it lasted forever and handled all the power he could ever throw at it but I feel a double is better suited to a street car.

 

I still don;'t understand why people think triple plates are less so for a street car. THey are easier to drive than a twin plate so why would anyone prefer a twin plate for street?

 

How would a triple plate be easier on the drivetrain, could you simply use a less extreme pressure plate and allow the clutch to take more wear because its transferring the power over 3 plates rather then one and a strong pressure plate? Also assuming power levels close to 300whp about how much life could one expect out of a triple plate setup if driven correctly.

 

exactly fury - more surface area means you can use a lighter weight pressure plate...we've got all teh details on these on our site if you ever want to read up on the differences.

Dan - Cusco's twin actually uses carbon lined disks now.

A triple for 300 hp is pretty sensless truth be told....tremendous overkill for that kind of power level.

Mileage wise is so hard to say as its dependant on the driver.....but I see no reason why a twin or triple could not go 60k plus miles on a set of disks if driven properly.

 

The ATS tripple carbon would be tripple nice, but at tripple the price... If I had the budget, it would be the only clutch for me. I'm not a mathamatician (obviously can't spell either), but I'd bet a tripple could use less clamp pressure than the OE PP and still hold well over 400ft lbs of torque... well pasted 60k miles. Again, the clutch is A+, the price is reserved for the top 8% of Evo owners though... don't get me wrong, looking at the pics of the ATS does for this old man what Viagra (sp?) does for others

 

LOL Zeus. Yes Fury, as Adam mentioned you use a lighter presure plate and you have more give between the greater number of plates and thus a smoother takeoff. Bottom line, triple plate is always easier to drive than a twin all other things being equal. The ATS clutch is a full carbon composite disc. I'll have to see a Cusco clutch myself. Next time take a few pics of the Cusco Adam. I want to see. Oh and tell Cusco USA. I asked them again yesterday and they said, they still don't make any carbon clutches.

 

Silver evo, I now have the twin disk when I put it in I will let you know how well it will perform.

 

You will be seeing my Cusco twin disk either late this week or early next when you do the installation. You have my permission to take all the pics you want of it

Okay Keith. Sounds good. Thanks!

 

Hey Todd, did you get it from Boost Solutions? I was there talking with George the other day and he showed me that ATS clutch. This is why I started this thread. I want toknow as much as I can about it. When I was talking about it with some guys at work they came up with the news that carbon clutches wear out rapidly.... I thought I ask around and find out ppls experience with those. They look very nice and are light, etc. But it would not make sense for me to get one if i have to replace the pressure plate in 20K miles....
Please let me know how you like yours and lets see how many guys have had those clutches in the past and how long they lasted...
