Ive never tracked my car, launched it, auto-x'd it, nothing. Some spirited driving here and there, but nothing to really cause this. Installed to torque specifications and double-checked torque at 5k miles. Ive driven a variety of pucked clutchs. This was one of the worst. I like my friends solid 6 puck better than this. This thing moves the engagement point on the pedal up and down between 1-1.5" all the time.



Im driving from my new apt (which thankfully has an attached garage) to my old apartment and slow down for a truck in front of me making a turn. I downshift to 2nd like I would any other day, give it enough gas to build all of 5psi, and go to shift into 3rd at about 5k rpms. About halfway through the stroke the pedal crunches then drops flat to the floor, and locks me out of all the gears. Now, I’m not in a good situation here, cruising down a road with the only place I can fix this car about 10mins in the other direction. I coast to the intersection ahead pumping the clutch and trying to rev it to get it to go into 1st. I grind it, but manage to get it into gear while I’m waiting to make my turn. Coming out of 1st had to be the most difficult thing I’ve ever done. The clutch started to grab, then it totally let go, then it slipped horribly and let out this shrieky metallic noise. At that point I knew something was seriously wrong and I needed to get home ASAP. Sadly, I had to go through this ordeal of shifting again. Got up to about 6k in first and pushed the pedal again. This time it resisted, then dropped, then started pulsating (like I was pushing against crunching metal). I skipped 2nd and went strait for 3rd. I tried to just pop the clutch but it slipped again, this time worse than the first, the whole while giving me that wonderful metal shrieking noise. I drove the rest of the drive in 3rd, speeding and running a red light and a stop sign on the way. I got stopped by the gate at my apt complex and had to shift back into 1st. Same ordeal as before, except now my pedal was shaking as I pushed it in. I drove through the complex in 1st gear and killed it at my garage door, where I pushed it in. I hope the pics help. Im glad the spring fell to the pressure plate side and not the flywheel side. Obviously I glazed the hell out of the flywheel on my way to the garage though.





Cliffs - Spring fell out of clutch, jammed in pressure plate, I glazed the **** out of the clutch and drove the whole way back home in 3rd gear. 12k miles on an untracked clutch. Spec sucks.

I got a spec stage stage 3 with the spec light weight aluminum flywheel. I've got maybe 20,000 kms on it. I autox the car hard. I road race the car hard (time trial HPDE racing). I drive it everyday in traffic stop and go traffic. I have a racing beat engine torque brace (I have a 2nd gen). Delrin differential mounts (basically solid). No give on the driveline. I have had no problems with my clutch. I had to replace my tranny with a spare about 3000 kms ago and looked at the clutch. Everything was in very good shape.



I think you should talk to SPEC and see if there is a warranty. They are good for customer Service I find. They gave me 25% off when I said I race autox and HPDE in Canada if I ran their sticker.

Get an ACT 6puck with the extreme pressure plate. You get a long life out of it. Hell, it held up to 520lbs of torque for me. That was its limit though. I now went with the Exedy Triple Disc.
