Break-In Experiences:
0-10 Miles ~ Clutch pedal travel was off so I had to adjust clutch pedal travel. Fixed issue.
10-100 Miles ~ Clutch was real grabby with lots of chatter and made some TOB noise with clutch out. I had to install a 9lb. clutch fork return spring to pull fork back when clutch was out. Fixed issue.
100-500 miles ~ I took it real easy during this time. I had to rev to 1700-2000RPMs for smooth quiet take-off. I couldn’t feather the clutch very well yet. It worked best to just let the clutch out at higher R’s and just go. There was still quite a bit of chatter when pulling away or creeping slowly in traffic.
500-1000 miles ~ I got a little more aggressive and floored it a few times. Everything held great with no slippage. Now clutch doesn’t slip, but tires will spin a little at about 4500RPM’s in first. Found the sweet spot where the clutch engages; it’s just before half way. I could now at least do a “clutch stand” on a hill at 1000RPMs with no noise.
1000-2000 miles ~ The clutch finally started to feel like the stock one again and has quieted down a lot. It only clicks or chatters a little when it’s cold (below 32F) until it warms up. Clutch engagement is smooth as the stock one was, but this one has far more grip, especially at high R’s and on shifts. I can now roll off the line from ~1200RPMs with very little chatter or driveline vibe.
All in all I’m very happy with this setup. It has held up to my expectations so far. I will say that at first; I was a little concerned with the noise and the way it grabbed off the line and on down shifts. It was real jerky and you had to rev match perfectly; which was hard at first with the flywheel, it makes the gas pedal real touchy and the RPMs just kind of hang up high for a split second longer on shifts. I found that if you just don’t completely let off the gas when shifting up or down it will engage a lot smoother.
The Lightweight Flywheel makes for a little gear noise on vibration at times. Since it doesn’t have a Dual Mass design it won’t dampen as much noise or vibration, so you should expect to hear more chatter on take off and some rolling gear noise when you let off the gas and coast or use the transmission to slow down. I usually only hear it in 3rd and 4th gear above 2K RPMs. It all sounds and feels pretty rough in the beginning, but it hasn’t slipped or spun on my yet so I guess we’ll see how long it lasts.
** Pictures won't upload so I will post them with copy of review in a Transmission thread.

After 84,000 miles on my Spec 2+ I now have a Spec 2 in the car, with 400 miles it. It feels nice and has not chattered once. I'm getting close to the end of the 500 mile breakin, so I haven't abused the clutch yet. But I'm very happy with the way it drives. I had no issues with the install or any issues like the other guy had.
