I'd recommend getting a shop manual.. and checking the forums for tips/tricks/things to look out for.

Now give me your clutch plz

Nope, those aren't the springs I'm referring to...

This is...



Sorry for the confusion.

The spring shown in your pic is really only there to keep the separation between each disk and their mating suraces even and to minimize dragging that would lead to syncro wear, etc. That spring in no way reduces the chatter associated with twin plate clutches. The chatter that occurs is when the floating flywheel is tapping the posts on the fixed flywheel while the clutch is disengaged. It is especially noticeable when the clutch is cold since the tolerances are greater. As both flywheels heat up the tolerance shrinks and the clutch quiets down.

The spring shown in my pic dampens torsional loads when the clutch is engaged. It allows the input shaft spline to rotate independantly from the clutch mating surface, albeit only for a short disntance. This small amount of freedom of movement helps keep torque spikes from bring transmitted to the transmission input shaft when you dump the clutch between shifts, off the line, etc.

Cheers,
Drop the price and I will, no offense, I think you make an excellent product but I still can't justify the price.

This is not always the case though, as you can buy full face metallic disks without a marcel spring although they are rare. Also, pucked disks generally (not always) increase torque capacity of a clutch, since the PSI on the disk is higher given the same clamping force. Since the force of the pressure plate is applied over a smaller area, the PSI (pounds per square inch) is higher. FYI, the marcel spring I am referring to is not the set of springs mounted radially around the input shaft spline. Those springs are there to minimize shock loads to the driveline by absorbing torsional shock loads.
Nice info. Thank you!!

I just read this whole thing...My stock clutch just went out, I dont plan on moding my car heavily, maybe exhaust but for now its all stock, what clutch will last the longest? The ACT or the exedy twin disc? I like to launch hard on the street and I might take the car to the track... I have no clutch right now its so gone that when i let the pedal all the way out it wont grab at all, it was engaging at 5k and now i can rev it to the limiter and it wont move in 1st. anyways i need to order one or the other tomorrow and I am not wasting money on another stock one that will go out in 11,000. I bought the car used with 9,000 and less than a month later my car has 11,000 and the clutch is gone.

thanks
nick

Nick, you're going to get mixed answers depending who you talk to, some who love the ACT and hate Exedy, and vice versa. Personally, if you want the cheapest twin disk clutch that's worth having, I would buy the Cusco twin, it's made by Exedy, but the pucked disks and the compund they're made out of seem to last longer than the standard Exedy twin. You could also buy an ACT, which will also work well. You don't have a lot of mods, but you drive aggressively so you need a clutch to match. The ACT is definately an improvement over the stock clutch, and so is the Cusco. Buy what your pocketbook feels more comfortable with, neither will dissappoint.

Six puck clutches usually wear a little faster then the full face so I can't see how the Cusco twin will last longer then the Exedy semi-full face cerametalic twin. Both should last a long time though.

Steve, I did find the Exedy version of the Cusco clutch in the catalog that came with my twin. I think it is called the hyper R clutch or something like that.

I installed my Exedy twin this weekend and it is amazing. The shifting action has become so smooth. I have not had any of the problems others of had yet. But I have only been using this clutch for 2 days now.

After installing one, I could see where some problems could come up if the directions and torque specs are not followed.

The puck clutches I've had have lasted longer for me, but maybe it has to do with my driving style. I rarely wear out a clutch, I'll burn them up first. I prefer to slip a clutch more to save the drivetrain than dump it and put shock loads on every part of the drivetrain.

I wasn't aware of an Exedy version of the cusco clutch, good find!

I too have had no issues with my Cusco twin and I've put nearly 4000 miles on it. And I have to agree with you 100% that if the instructions are not followed properly, there will be issues. I think a lot of people have had their Exedy clutches installed by shops that didn't truely know what they were doing. They may have understood the concept of installing the clutch, but the time spent on setting up the clutch itself properly is very important IMHO.
