1 think i wanna add. you guys are just talking about flywheels @ 8 lbs, but like the stocker is 28lbs s4 t2 and 24lbs S5 t2 but those include the counterweight in those weights. So really, isnt it 8lbs + counter weight @ 4-5lbs, thus realistically making the flywheel like 12-13lbs? Just a thought.

That's correct.

I really wish they'd publish polar mass moment of inertia values for the flywheels, since that's what really makes the difference. A heavy flywheel with the mass concentrated in the middle can feel ligher than a lighter one with the mass concentrated at the outside, so just knowing the mass is only half the story.

even a lightweight flywheel with the clutch installed is still going to be easily over 20lbs so it's isn't as drastic as some people make it out to be. the counterweight is also over 3 lbs by itself.

Yeah that would definitely be helpful. Is a performance clutch generally heavier than a stock clutch? I know the carbon ones aren't.... but that is a different story

I have no idea. The 7.5" and 5.5" racing clutches will be for sure, an organic performance disc is probably about the same, a puck clutch should be less.

i run an os gilkin twinplate which has a 9lb flywheel. revs do change very quickly. takes a little getting use to however id reccomend a light(er) flywheel to anyone

now a grabby twinplate..

Multi-disc clutches are usually smaller diameter, thats part of the reason for using multiple discs. Moving the concentrated weight to a smaller radius reduces the polar moment of the assembly.. which will result in faster acceleration, even if the mass may have gone up because of more material to support multiple discs. So this would be one example of performance clutch reducing the 'mass' (the important part, the polar moment has been reduced..)

Is it harder to drive a turbo car with a light flywheel/performance clutch setup? I was able to get accustomed to the 8lb and heavy pressure plate pretty quickly in my H22 Prelude

I prefer medium weights. Superlight is too light imo, but stock is too heavy. I like the 12-15 pound range flywheels

i loved my lightweight flywheel in my prelude as well. but i think those are totally different machines

I myself prefer the 12-15 lb flywheels.

I don't think so; I actually think its easier. I upgraded to the Racing Beat Aluminum Flywheel (12 lbs total w/ counterweight) for my car, and I loved the results. I never drag the car (besides the occasional stop light run) and use it for autox/road race. Revs much more freely and very fast (first gear goes by almost instantly) and its so much easier to keep the revs up high on the track. I especially loved how much easier downshift rev-matching was after I got it. I highly recommend it.

Yup, lightweight flywheels are highly recommended for road/circuit driving. For drag however, they may be downgrades.
