I just had Pep Boys install my Spec stage 2 clutch and the thing is awesome. The labor was $440, less than most small shops around here, the ones that were willing to install user supplied parts anyway. Most shops wanted nothing to do with non-OEM parts. I guess they wanted to sell their overpriced OEM crap.
The clutch pedal was so light, at first I thought something was wrong. It's much lighter than the OEM clutch. It really grabs hard too. It will take me a few hundred miles to get used to it, but I love it. Hopefully it will stay this way.

Make sure you break the clutch in before you abuse it.

This is the first time I've ever brought my J in for work. I was ready and willing to change the clutch on my own, but my dad didn't want all that crap happening in his driveway, and he who owns the driveway makes the rules. On the plus side, the labor wasn't totally unreasonable and I don't have any of the problems that other guys with these clutches do. Engagement and disengagement are 100% and the pedal got way lighter.
