I'm going to be doing a clutch soon on my 05, 85K on it. I wanted to know if I should go with the light weight fly wheel while I had the chance.Is anyone out there running one on the street,if so do you like it or was it a mistake. The cars main use is a high speed commuter car.Thanks in advance.

You lose a little bit of drivability, especially at very low speeds. You can rev up faster, but it also loses revs just as fast. It's a give and take thing, if you don't mind having to mess with the accelerator and clutch a little bit more then go for it

With a lightweight flywheel it's easier to stall the car out. It's also harder to launch and I noticed that it is harder to build boost in 1st gear from a roll. On the other hand, the car pulls noticably harder in the lower gears. I'm using an ACT Prolite. And ACT Streetlite might be a better compromise...

Yes, but its not any faster from taking weight off of the flywheel. Taking weight off of the flywheel means that the engine will be able to turn the gears faster at lower speeds than the stock flywheel and power will be applied faster, the key word here is applied. However it will not be able to keep that rate of application the higher the revs go. The power applied makes no difference as much as the rate at which it is applied.

Think of it like kicking a balloon versus kicking a basketball with the same appplied force. Kick the balloon and its initial acceleration will be faster than a basketball but it will not travel as far. Kick the basketball and it initial acceleration will not be as fast but it will be able to sustain that speed for longer. Bottom line is that you will have to kick the balloon more times to reach the same distance as the basketball.

edit: this is kind of one of those subjects where you have a people that like them and people that do not. its kind of like asking which is the best turbo or fmic or floor mats. the best thing is to find someone in your area that will give you a ride or maybe(not that you will find too many people that will do this) find someone that will let you drive their car. my opinion is that if you like the way that your car drives now then dont change it. if you want your car to feel to a lesser degree like an on/off switch get a lightened flywheel. i had one on a previous car of mine and took it off after a week. to me the car was just not as enjoyable to drive.

the stock flywheel takes more energy to put it in motion but its higher rotational mass gives it greater inertia. i'm not a fan of lighter flywheels.

I guess I'm the only one that loves not only my SUPER light flywheel but my SUPER light clutch as well... 19.5 lbs total (pressure plate, flywheel, disc)... which is the same weight as just the stock flywheel by itself ... or about 17 lbs lighter than stock overall weight of the pressure plate and flywheel assembly (about 36 lbs).

THE ONLY negative in my humble opinion is the increased noise... If someone knows of a way to get rid of that "chug chug chug" sound on deceleration, please let me know.

Thanks for all the replies, I think with all the stop and go traffic on the way home (70 miles) I would be crazy to run the lightweight flywheel.You guys just saved me money and a headache, thanks again. Steve.

i allways thought it was a momentum thing where if you had a light car you need a heavy flywheel and if you had a heavy car you needed a light one when i mean car i mean engine

the lighter your car, the lighter the flywheel u can get away with since it takes less stored energy to transfer from flywheel to drivetrain to get moving.

I got the ACT HD clutch and Gruppe-s flywheel (14lbs) and im in northern VA traffic everyday, no problems for me. The car revs a little faster, and from what I can tell it builds boost faster also. I have no problems with noise or chatter.

running the act 11.5 lb and i love it

I'm absolutely not an expert with respect to AWD cars and lightweight FWs and/or performance clutches. However, when I was dragging & driving a 96 Prelude, an RPS stage 3 sprung hub clutch and Fidanza lightweight FW was, HANDS DOWN, the most fun and rewarding mod I ever did to that car. Sure, you have to relearn how to properly drive your car, b/c, with the right clutch, you will meet a friend called "clutch chatter." If you're in gridlock traffic, you will experience displeasure in your calves, as you carefully "slip" the new clutch in & out...and you WILL stall for months...maybe even years, 'til you REALLY learn how to drive your car.

That it, I'm going for it. The car is at the shop now and between the last few posts and Phil at XX I'm going lightweight. I'll give my driving impressions on sunday after a full day of playing!

I hope you have a way to turn off the misfire codes...

[BLACKOUT]

Uh oh...codes, =(. Are codes guaranteed?
