Exedy Twin too much for DD?
The Exedy Twin HD was my favorite DD clutch, and favorite clutch I have ever drove in an evo. The only downside is they don't handle launches with high horsepower. They tend to be toast after 40+ launches. obvioulsy a stock turbo won't blow the Twin, but a high tw car making 500ftlbs will blow through the twin much quicker on launches than the triple. The triple disapates heat better. The Triple is almost as DD friendly at the Twin, except the chatter is twice as much. just my 2 cents

I've my HD twin for 12k miles, about 1k worth at the power level in my sig, 11k or so at 330/340. After the 1st trip to the track it is now slipping. I'll be putting an ACT 6 puck in as a replacement. Not sure what the life expectancy is on these things for a car that is daily driven, but I am not happy with it, many of my friends easily get 25-35k out of an ACT HDG6 with MUCH higher power levels then I am at, launches, track time, the works without issue.
I believe I am starting to experience the drag. All the symptoms appear to be present. Roughly 25k on the clutch running full Holyoke and meth. Though only a few passes...I'm going to try to bleed the clutch line to be certain. However, once the car is started putting into gear can be difficult. While driving there is no issue. Only when stopped...BTW this did not seem to be a developing problem. More or less came out of nowhere...if this is the case makes wonder if it's worth the cash for the twin disk setup...yea it drives nice but if it's toast this early with what I would call a product failure and not by means of being excessively worn out, why not get something else...

as it sounds like the same issue I was having when I thought my twin was going bad, getting back into gear when I stopped at lights and getting into reverse when parking, but once I got the car rolling no problems. And they are pretty cheap maybe $50 at autozone or closer to $80 if you get one from Mitsu. But you can actually go to the distributor (whose name I can't currently recall but I can find out if you want to know) online and get them both for like $90 I think I paid.

Theres a huuugge thread on here that describes how to do it and has pics. Depending how it was setup previously, as the clutch discs wear you need to readjust it to make up for that wear.
Look for the thread and try it out
I had SD twin for about 30K miles and the HD for the last 20K or so. Not going with any other (even locally produced ones) since these are working so well for me. With my short-throw I could shift so quickly I usually beat on more powerful cars between gears.
As the title states, I'm wondering if an Exedy Twin is too much clutch for a DD IX with about 320awhp. I came across a great deal on a used Twin and will be rebuilding it and installing it since my current clutch is slipping badly. I'm asking this because I've read in a few threads that the Twin has "way too much friction" for DD situations and will wear out very quickly. I didn't seem to think that this was the case but I know absolutely nothing about clutches so any help will be greatly appreciated!
I did adjust the clutch pedal with no luck. I'm going to bleed it shortly. The adjustment did not make a difference though.
Hey tigeryellow if you could Find that information, it would
be greatly appreciated. Thanks

My boyfriends evo has an Exedy Twin thats he dds he loves it and I love it too way better then the 6puck I daily, hes starting to get slip now at higher rpms(hes making 654/540ish ) so hes doing the triple disc conversion, onve my clutch goes out I will be going to the exedy twin.
Not that I am an authority on the matter but I do agree it's a great clutch. Great holding capabilities and great feel. Easily daily driven, however this premature failure that many have experienced is something to consider when dropping 1500+/- on a setup. And if you are payi g someone else to do it just think of what your annual or bi-annual cost of maintenance cold

It took me a minute to find but here is the website: http://www.phoenixfriction.com/c-318...-products.aspx
This is where I got my replacement master and slave cylinder parts from... best $70 bones I ever spent man. And as irony would have it the company Daikin is a sister company that branches off of Exedy so I was basically just replacing my oem parts with exedy parts to marry up with my twin. Awesum Right
So KABOOM... it's there if you end up needing it man. 
I would guess that most people on this board always have the intension of making more horsepower. I would say you can expect the stocker to start letting go in the 300AWHP area once you start getting to the track and depending on driving style. So why not go with the twin early and have the clutch to go with the power down the road?
I have resolved my issue. Having excess knowledge available on potential failures such as dragging clutches and worn out master and slave cylinders was the worst case scenario, based on the given symptoms. This had me losing sleep thinking I was going to have to get under the car and pull the trans again...When all it required was a good bleeding and a little pedal adjustment for good measure. I believe the combination of not having it bled in a year plus in addition to probably having introduced some more air while doing the brakes was the culprit...hope others are as lucky as me.
Cheers
