I am about to do a clutch and flywheel replacement on my 93 Prelude Si with the stock JDM 2.3 and 5 spd transmission. Whoever owned the car before me could not drive a manual so therefore warped the flywheel and it chatters horribly (especially on hills). I figured instead of going OE on these parts I may as well get something a step or two above this. I was looking at an Exedy Stage 1 clutch kit and the Fidanza 8 lb flywheel. Here are my questions...
1.) What are the downsides to having this lightened flywheel?
2.) I see Fidanza makes a clutch kit as well which is about 6 bucks MORE than the Exedy. Are they any better, if you had to choose then Fidanza or Exedy Clutch?
Please only personal experience (meaning if you have used them) answers only.
Thanks a lot for any information/suggestions.
1.) What are the downsides to having this lightened flywheel?
nothing, other than a slight quicker drop in revs. mine didn't make my car rev any "faster"
2.) I see Fidanza makes a clutch kit as well which is about 6 bucks MORE than the Exedy. Are they any better, if you had to choose then Fidanza or Exedy Clutch?
i bought an exedy organic clutch, if i were to do it again, i wouldn't because it doesn't grab any harder than the stock one did. i have driven a prelude with a competition clutch and an ACT clutch. i like competition clutches. just a tad bit more bite.

i have an 8 lb fidanza flywheel too. i think its more in your head.
i attribute the feeling just like SS brake lines. when i put them on, it didn't feel much different. when other ppl put them on, seems like more ppl say it works.
i say its more of the fluid flush / re-bleeding of the system. this is much like flywheel/clutches. you normally just don't put in a flywheel, you usually put some other stuff in there.

Doesn't rev faster? No way. You are reducing the weight of the flywheel --> less rotational mass = easier to turn.
It does indeed rev faster.
You will also note that with a lighter flywheel when you lift from the throttle, the car will decelerate faster as well. A stock (heavier) flywheel will decelerate slower because it has more rotational mass (keeps spinning due to it's weight). Because of a lighter flywheel, the clutch will feel a lot 'stickier'. It will have a much easier time grabbing the flywheel.
Changing to an 8lb Fidanza flywheel has been one of my favorite decisions in modification.
^On paper yes, it does make total sense. I don't doubt that it will help but the magnitude of "help" is something I take with a grain of salt.
I'll give another example from this weekend when I got rid of the prelude.
We were at dyno day and another luder was talking about how the mechanic will stall his car because he has an 8lb flywheel. I think it has to do more with the position of his clutch engagement because it was adjusted and didn't really feel stock. I mentioned I have the same Fidanza 8lb flywheel and the other guy who drove the car was surprised that I did. Its because he reads experiences online about the flywheels.
The one thing I did notice was it dropping in rev's if I clutched in. It was slightly faster drop down, accelerating up the rev's felt about the same.

so lighter flywheel means
+ lighter(weight redu.) revs faster, inturn theres more whp
- revs drop just as fast, if too light=annoying DD, can be a pain when braking in a new clutch at the same time.
