Rev points at shifting are determined by gearing, not the flywheel. The flywheel will only affect the timing of how fast the engine sinks to the correct RPM for the next upshift. This means with a lighter flywheel you'll just be working the clutch & shifter faster than before. Additionally, there is less rotational mass to synchronize, making things a bit easier on the clutch & synchro's (though not by a lot I imagine).

The tradeoff is that it's easier to stall the car, and hill starts can be more tricky, but those are pretty minor concerns.

As I mentioned before, I never hesitate to go to a lighter flywheel when I have to pull the transmission on one of my toy cars, because that flywheel was designed more for Mr. Everydayman, and not for the most enthusiastic of driving.
Thanks. I realize the shift points don't change, it's just the revs would drop too fast and fall out of VTEC. I'm pretty quick but I find myself falling out sometimes if I don't nail the shift quickly enough. I don't know how much faster the AP1 flywheel spins down and if keeping it in VTEC is even a possibility with it or would I find myself falling out with every shift due to the revs falling too fast.
The flywheel on my AP2 is lighter than the stock AP1 (9lbs IIRC). Now that I am s/c I find myself blipping the throttle to match on some upshifts, but I don't recall needing to do this much before then. Certainly you can go too light and every car & driver is a bit unique. Go with what works for you. But I think most people that go to the AP1 flywheel on the 2.2L are happy with the result. I plan to go heavier next time the trans has to come off. Adding the s/c load made a significant difference.

Anyone have actual experience with the exedy oem replacement clutch kit? People keep saying it's trash. Is it really that bad and if so what about it is so bad. I bought one recently haven't installed it yet. And before I do I'd like some actual owner feedback. How does it feel sound look? Does it do better worse or the same as stock? Please let me know also I got an act streetlite 11 lbs fw.

Some highlights from above:

If that pp doesn't say Honda right on it, then your issues don't surprise me at all.

This comes from one of the most experienced S2000 tech's on the planet. Return that Exedy while you can (hopefully).

Glad that came up before I spent my money. I was under the impression Exedy was identical to OEM.
