Busy couple of days. Finally ditched the sucky dual-mass flywheel that has been plaguing me for 30,000 miles. Lots of work, but so, so worth it.

I can be annoyingly verbose about my thoughts on transmission/shifting feel, so I'll do that in my own thread, likely in the next few days.

ACT Streetlite Clutch PN BM15-HDSS
Turner Lightweight Single-mass Flywheel (19.2lbs) PN 026647TMS01 (Bought the kit on sale for ~$1200 out the door back in February
FCP Shifter rebuild kit - All OE stuff, there's a good deal of things additionally needed too if you want to replace everything.

Largely followed this DIY. All hail FCP.

Also, EfThreeOh's DIY post here

And this post for bellhousing torque specs - I found a lot of conflicting information, but after yielding the aluminum bolts I have confidence that this was correct.

I also did just about all of the "while you're in there" type stuff. I replaced and doubled up on shift shaft seals, I think it was a spidertri post I learned that trick from, so thanks dude!

All of the transmission stuff is now perfect. With all the other minor transmission mods and input/engagement mods, it feels like a proper '90s car now. Outputs match your inputs, whether you botch a shift or nail a rev-match. No trickery or NVH BS. Blissful gentleman's sports car. Such a keeper.
