This is my combo, AP1 flywheel, OEM Honda disc, Spec light weight (4 pounds less than stock) pressure plate, and AP2 transmission.
Basically this is an equivalent to a 10 pound flywheel. The setup is super easy to drive very smooth and no dramatic difference in RPMs rising fast or dropping fast. Peddle feel is a bit lighter than stock but grip is improved by 20 to 30% using the stock friction disc.
That's a great looking setup. I have that same PP but with the Spec disc as well. I've been thinking about swapping back to the stock disc for a while and it's good to know that it fits. I actually tried this combo with both the stock AP2 flywheel and the Fidanza flywheel. I ditched the Fidanza. It didn't provide any noticeable benefits, but did have some drawbacks for a daily driven car.

We just installed a full Spec stage 1 setup in a 2002 over the weekend. I drove the car today after the owner broke it in this week.
It is a little more grabby than with the OEM disc but, still very easy to drive. I liked it allot

My setup is so easy to drive a 16 year old girl just learning stick would have no problems driving it, it is easier then stock.

it seems like ppl are saying w/ a lighter flywheel it'll rev faster. i have 4.77 and it already rev's pretty fast, will it go even faster now? i'm literally going to be shifting like a madman? lol
also, due to labor cost, it doesnt seem wise to change unless i replace clutch as well. what clutch is recommended w/ aftermarket lightwheel mentioned and usually at around what mileage should i be replacing the clutch under normal wear?

my buddy keeps telling me that a heavier flywheel is better for drag racing since each time you grab the next gear there is more umph smackin the clutch. he heard it from one sponsored drag racer so now thats all he swears by.

the basic he says, is two identical cars going straight all out, the one with a heavier flywheel will lurch a bit forward after each shift compared to the one with the lighter flywheel.

im going with an ap1 flywheel cuase i dont buy this crap and dont care even if there is slightly better for that, since i want all around better driving.
I don't claim to be an expert in physics, truthfully, I don't like physics and wasn't that good at it, but your friend's argument is not really valid. if there were identical cars, but different flywheels, the car with the heavier FW will lose more power due to the additional weight of the flywheel during acceleration (contributing to added parasitic power loss). Granted, the momentum generated by a heavier flywheel maybe beneficial during gear shifts (which i believe is your friends argument). A lightened flywheel would be more responsive overall and would be relatively better in certain aspects. Again, I'm not a scientist and I'm not claiming to be... anyone else chime in?

Sweet, I knew that A- I got in Physics wasn't a sham.
