Was just looking at a Cusco twin disk. Noticed the disks were totally different. It had 2 of the 4 puck disks without hub springs. The rest of the clutch looked the same as the exedy twin disk. Seems like it may have more potential for chatter on first gear take off.

what are some examples of mileage intervals at which the hyper single or twin needed rebuild?
If I install a new one, how long can I expect (no drag racing, no track) this will last, before it needs maintenance? I am 20% below the torque threshold of this.

All depends on how you drive. If you drive like grandma then a very long time. As a friend had a friend with an evo drove like grandma. You drift and hang it out there. Generally you can see 25k maybe less. Racing people often check their clutch once a season.

Act monoloc is freaking awesome! Locks the tob without having to use a clip on the back the fit on to the tob is amazing! I don't forsee having any problems with using one. I recommend it to any of you guys or anyone using a pull style clutch.

Also I think it was a good idea of mine to weld the center hub. Also I noticed the twin disk hub part on the cover part will chatter and move. Compared to most clutches out there. I thought that was rather odd.

Twin disk friends. Recently found if you search the "exedy (part number)" of the clutch part you may find cheaper prices on eBay.

Been messing with clutch pedal adjustments. Been finding the exedy twin disk may require more distance to travel in order to disengage. Just a FYI for my fellow twin disk users. I was able to exceed the oem adjustment but using the jam nut all the way to the bottom and jam it against the shaft where there are no more threads.

Old but good thread bump,

Did you bring the throw rod for the pedal way more inward, and the jam nut is all the way at the end?

I want to make sure I am reading your comment correctly.

I have the Exedy twin disc also, I didn't put it in, Was there when I bought the car.

The clutch engagement height of the pedal is user preference, but generally speaking the best way to set it up is as follows:

1. Resting height at or slightly below the brake pedal height.
2. Disengagement height near the top of the travel, but not immediate (keep reading).
3. Pedal stop installed to eliminate free travel beyond full disengagement.
4. Free play from resting position to the start of disengagement.

If you neglect 4, you WILL trash your clutch in stop-go traffic as the system heats up. Basically, it will slip the clutch at all times if this happens. If you ever feel a total lack of free play between resting position and clutch disengagement - your disengagement is set too early.

Also keep in mind you're juggling multiple sensor positions in this whole mess too - the Subaru pedal setup is not fun to adjust but at least the DBW throttle eliminates one of the three.

I have reason to believe the previous owner had clutch installed wrong or did it wrong himself.

I noticed two paint parks don't line up.

It chatters really bad at take off, I can hear it under the car, it shudders. Also I have been having a lot of trouble taking off since I got it, No RPM seems right.

Lastly, the shifter won't go easily into gear when stopped. The car does not roll though.

So I wondered if they have the disengagement set right, I wonder if it's been slipping some since..who knows.

The other day I down shifted/rev matched 6th to 5th and was greeted with the rev limiter... So I am going to rebuild this clutch, properly install it and see what happens after that.

I have a new fork, TOB and a clutch M/C, Which I need to remove that plastic piece I have forgotten the name of, before I install it.
