ACT have had nothing but problems, and if you look around on some of the dsm forums, you'll find the exact problem that happened in the first post.

I really don't want to get into clutches too much, but I tend to disbelieve your statement on holding harder AND being more comfortable on your leg. And how did the fingers not fully release? Could you explain what was blocking them from fully releasing? Of course you will see the same problem happening on other forums. When 90 percent of DSM's run ACTs, and your using a sprung hub that is for "street" use and make 500whp, you are going to run into problems, plain and simple. Find out the percentage of ACT problems to other clutch brand problems by amount of people using them, and see what failure rates are. Then talk.

Clutches cannot have a soft pedal effort and have a high clamp force on a clutch disk. It is NOT possible. Sure, you can move the "pivot" point on the fingers in or out a little bit, but not enough to be able to say it holds harder and is more comfortable on a leg. You can also use a different clutch disk material, which southbend seems to be doing with some success.

Seems to me like most people have gone wayyyyy faster on a ACT clutch in a DSM than any other clutch. Anything to disprove this theory?

Any exactly what vehicle did you use a "Competition" brand clutch in?

Says who? Lets see your proof on the whole fast dsm act clutch theory. They are good clutches, dont get me wrong, but you should post as much proof as you expect him to.

I assume this was directed towards me, I drove a Stage 2 Competition in a S2000; the pedal preasure was lighter than stock and it engaged nice and solid.

Of course people have gone faster using ACT, its b/c there are far more in use since they were pretty much the only clutch available until recently that could hold big power; this is simple statistics. IMO, using a lighter preasure plate with a higher friction coef. disc is a much better design than a heavy preasure plate with an OEM-style disc. Enough of this though, everyone has their own opinions regarding clutch choices and its probably been covered at least 20 times on this board. Everyone should use what they like, what they are comfortable with, and what they can afford.

dumb_ricer-

Actually yes you can have a stronger clamping force by making a disk that creates alot more friction. The pedal pressure was lighter because by using a feramic/kevlar lined disk. It is alot more grabby, so engagement isnt as smooth but Id rather have than than wear out every component from the fork, master/slave, and pedal assembly- which all had to be replaced after I had the 2600 in there for a while.

And the fingers on my old 2600 somehow just would not fully disengage the clutch. Its like the spring in the fingers wore out.

We all have our opinions... you can stick with act products, I will not.

Have you driven a car with a Southbend clutch? They hold just as much torque if not more than an ACT equivelant, and are a TON easier on your leg. After driving both I swear by Southbend, as do a handful of people on here.

**Halon** · 10-31-2006

My ACT disc is the revised one that's supposed to not have that issue anymore. I have RRE's X-Clutch.

FattyBoomBatty · 10-31-2006

I've had no problems with my ACT for 3+ years.

turbotalon1g · 10-31-2006

My southbend clutch feels as soft as stock almost, yet is rated to hold around the 350-400 lbs-ft i believe. I also had a ACT 2600 and that fucker would make u pay for thinking u could hold the pedal down for a minute a quick light.
If your gonna make statements about other clutches, make sure you have experience about them. That actually goes with anything. Since i have used both ACT 2600 and a SOuthbend OFE i qualify.

**Kracka** · 10-31-2006

I have the Southbend DXD in my Laser and I'm really liking it. The pedal preasure is barely any heavier than stock, its easy to drive in stop-n-go traffic, and engages nice and solid. I do still like my old Centerforce Dual-Friction the best though, it didn't engage quite as harsh as the DXD so it was a bit smoother for daily driving.

**Halon** · 10-31-2006

I had a SPEC clutch in my old GST that I really liked too. Before the x-clutch, I had a Pro Clutch with a sprung 6-puck in the talon. I also liked it because of the soft pedal. Anywho, different strokes for different folks. I'm liking this x-clutch also. I have yet to really get a shitty clutch from any vendor.

When it comes to pedal pressures, I swear most of you are wimps. I've had 3 cars with act 2600lb clutches. No problems, and the pedal is stiff but not THAT bad. I've never had a problem with ACT, always took the abuse I threw at it with hard launches and such. I've used OEM new Mitsu clutches, that worked nice for an OEM, I've used a few ACT 2600lb w/ act street disk, act 2600 w/ feramic disk, and Act 2600 with 6puck SPRUNG ceramic disk (the current one clutch setup in my new car). I love the sprung 6puck!

A//// Guy · 11-01-2006

No it really wasnt too bad for driving, except in heavy traffic... dealt with the 2600 for 2 summers. The pedal pressure is just another negative thing associated with a heavy PP. The major problems occur when it strains all the components between your foor and the actual clutch- master/slave/pedal assembly/fork/ball etc.

turbotalon1g · 11-01-2006

Sleepy anyone can handle any clutch, the deal is that our cars ran for more than 2-3 days at a time so we could actually feel the stiffness of the clutches.

Hoffer00 · 11-01-2006

I have a 6 puck ACT racing clutch and 2600 pressure plate. I have never had a problem with either. I would not recommend the street disk for our cars.

I agree. Centerforce is one of the best that I've personally experienced. Very good clutch.
