Act 2600 Vs. Cm 2500

[Khadgar]

Well I want to make the decision right NOW, but out of everyone I've asked its been almost a 50/50 division on ACT vs. CM.

So which do you think is better, and why?

This could be a long and heated debate, but I'll go first.

I have the ClutchMasters 2500 with the 4 puck spring hub disc and love it. I sat in an Eclipse with the ACT2600 and was amazed at how much more pedal pressure was required with the ACT2600, which is something to consider if you are concerned about crankwalk. Supposidly has to do with the fulcrum points CM uses which makes it easier on the pedal pressure, but still has 2500lbs of clamping force. I started out with the ACT2100, but as I started making some real power, it wouldn't hold. So I had a local tuner shop here order the CM 2500 with the segmented Kevlar disc. It worked fine until it got hot. If you slipped the clutch any off the line it would not hold the power (heat fade, who knew!?!?). CM swapped out the Kevlar disc for the ceramic puck disc for me at no charge. It will hold all the power I can throw at it (for now anyways).

You will get many opinions on this, so there's mine.

I am all for the 2600! I had one, loved it, and would buy again.

Anyone running the Southbend clutch? I saw they used Kevlar with theirs. Looked kinda like a Centerforce Dual Friction disc. Does Southbend's Kevlar actually hold power? As 1ViciousGSX said Kevlar clutchs on these car aren't known to be able to handle a lot of power or launches without starting to slip, even though the material lasts a very long time.

I had an old Stage 4 CM with a puck disc and it was my least favorite clutch. Lots of drivetrain noise, harsh engagement and the disc didn't last very long. It lasted the shortest of any of my clutches. I didn't really care that much about the noise or engagement, I was just disappointed in how short of a time it lasted.

The Centerforce Dual Friction would be my favorite if it could take a beating, but it can't handle a high HP AWD.

In my household I think we have gone through 2 stock clutches, 1 clutchmasters, 1 centerforce, 1 ACT 2100, and maybe 5 ACT 2600s. The 2600s on my 2G were always easy to push in, while the first 2600 on my gf's car was the hardest clutch I have ever driven on an import, but the second one seems easier to push in. I have a twin disc clutch waiting for my next motor.

I just want it to be able to handle launches every once in a while but be able to hold up so I won't have to replace it anytime soon. I doubt I'll be getting any HP figures above 300 with my big28

2600. I have driven a couple cars with them and plan to get one. For now I have an Exedy 1940# because I got it DIRT CHEAP! Cheaper than even an OEM.

Oh, and 1ViciousGSX, how does your puck clutch engage? I am just wondering, as I am willing to get something other than an ACT, it's just that I have already driven the 2600 an like it. Hooks when you want and you can slip it easily. From what I have hear ACT uses a really aggressive ceramic compared to others and it's not really street friendly, and that's the only pucked clutch I have dealt with so that’s why I ask.

The only issues I have with the 2600 right now is if infact it does promote crankwalk.
