Hey guys, compare the Exedy HD vs SPEC Super Twin for an '03- 5speed. It seems these are two popular and reputable clutchs

However, I also heard these problems being most commmon
1- exedy TOB poping out
2- SPEC needing new Master cylinder for the pull to push conversion, and also some clutch discs were out of measurement

Was there a solution to these problems, and are there any other problems that should be brought up? Help me make the right choice guys, I don't want to throw away 1300 again!

 

If you do not plan on exceeding 500wtq I would go with the Exedy Twin hands down.

 

The Exedy is a good street clutch. There's nothing wrong with it.

The SPEC is a push type, which is ultimately more reliable, and brings higher torque capacity with it.

 

I've had neither, but it seems the Exedy is better tested, more of them have been on Evos for longer, and people know thier strengths and weaknesses well.
I feel that the flaws of the SPEC will take more time to become well known.

Just a humble observation. (Don't flame me SPEC fans)

 

It's an accurate observation, however, until the SPEC unit became available, there was a need for a higher torque capacity, push type street-friendly clutch, that didn't make a lot of racket or cost an arm and a leg to rebuild.

 

Do you really think a new master is needed? I could see if the car had 100k miles but then almost any clutch will need one.

I've driven a couple exedy twin cars.... they feel great but make a significant amount of noise, don't seem to last that long, are expensive, and have wave lock issues.

 

Add to your list #3 - Quarter Master Twin that needs a rebuild every 10k.

There really are NO great twin discs for the Evo, it's so depressing that spending $1500-$2000 on a clutch and they are all still prone to the most annoying problems, frequent downtime, and pain the a$$ labor.

 

Current got Exedy Twin Plate HD installed in my IX about a month now. Feels really good a bit stiffer than stock, very fast engagement, does chatters a bit and the noise cannot be avoid. From I know, you might not have to buy a whole new kit and able to stick with the same one in the future and of course also depends on the condition of clutch in the future. Reason for that is, it could be rebuilt, Exedy has rebuild kits for it and also kits for upgrade to triple. Rebuild kits are not as much as a new clutch kits. only thing is labor but labor is something thats going to be there either getting new clutch done or rebuild kit.


SPEC clutch, dont know too much about.

 

ive owned 2 evos in my life and ive installed the exedy twin disc in both- i love that clutch and wish everyone of my cars would come with them from the factory!!

 

There are good and bad experiences with both clutches. I went with the spec mainly based off of what the LSx guys have said which is nothing but good things. If Spec can produce a great clutch for 600wtq that is easy to drive on the street and reliable for the v8 crowd, i put my trust that they can do it for an evo.

 

I have the exedy twin in my evo. Has about 30-35k on it. Still strong as ever and never misses a bit. I love that clutch!!

 

Did you resolve the shifting issues with the Spec twin? Did you run the Spec at the track yet?

 

The shifting issues have yet to be resolved. As far as a strictly street clutch goes the spec has the potential of being a good choice, but if you plan on tracking the car at all I do not advise using this clutch.

Two problems I experienced with this clutch at the track.

1. With the clutch pedal to the floor the car kept rolling forward on the 2step

2. Random lockout during lift shifting. No lift shifting from my experience so far is simply not going to happen with this clutch.

As soon as money allows I'm pulling this clutch out and putting an Exedy Triple in the car.

 

Exedy....less problems

 

FWIW, I have the SPEC and have no such issues.
