so im about to get replace my clutch probably to an ACT and then i started thinking should i also get a lightened flywheel while im at it. what do you guys think? what are the pros and cons of having a lightened flywheel.

thanks!

 

It depends pretty much on where you drive. A lighter flywheel will rev up quicker and the revs will fall quicker. That's between shifts and when you lift off. So, as always, it's a compromise.

I think for the most part, it won't hurt unless you drive up and down hill a lot. It will be a little easier to rev-match and your car will accelerate quicker.

Then it depends on how light we're talking about here. If it's a little lighter than stock then you should be fine. If you're going crazy light then it might be too much.

 

In my experience with a lightened flywheel on my Talon AWD, I had to bring the revs up higher from a standing start in order to get the car moving. It seems that the momentum to get the car initially moving is lost due to the lightened flywheel. I actually found it annoying in city driving. The pull to redline seemed easier, but I found no ET gain in my 1/4 mile times. Now I just had a Exedy Twin Disk HD clutch installed in my Evo and that comes with its own lightened flywheel and I'm having similiar issues from a standing start. I do have to bring the revs up higher when I release the clutch, but I guess that's the nature of the beast. I'm just so glad that I'm not getting locked out of high RPM shifting compared to my previous clutch set up.

 

i replaced my clutch with an act unit. i also got an exceedy 12 flywheel. the car revs quicker for sure and i did not notice and issue with getting started from a standstill. i would recommend it.

 

I have a Gruppe-S 10.5 lb flywheel no ill effects whatsoever. I do know that to light can be a ***** to drive my brother had a 7lb fidanza on his civic I hated it

 

I had an ACT 8lb. flywheel on my Integra and I doubt I would do it again if given the chance. Fast revving is fun and all but low-speed driveability was definitely compromised, making my daily commute a real pain. I can throw the Evo into second and crawl along all day, but I felt like I was riding a bull in the 'Teg, what with all of the bucking and lurching. If you do get an aftermarket flywheel, just don't go too light.

 

Its more annoying then its worth.

 

I feel you man. I had exedy metalic clutch in my DC5 a few years ago and that was pretty interesting in city traffic. To be honest 8lbs in a tegra is really going some. They have near zero torque to start off with so with really light flywheels things are set to get a lot worse in traffic.

I think though that the inertia in the evo's tranny is sufficient at a slightly lighter flywheel should be okay.

Oh, and I think it might be inportant to note that it's the combined inertia of the clutch and the flywheel that produces the end effect. If you have a heavy clutch (like a triple or twin) relative to the stock then it makese sense to reduce the weight of the flywheel. In which case, if the total inertia remains roughly the same the effect shouln't be noticable.

 

Dang a lot of us have evolved from Integras, lol so did I !!!

I had an Exedy cromaly flywheel in my integra, but liked the lightweight Clutchmasters better...

As for the EVO I stuck with the stock flywheel since the lightened one is not that much lighter, and also the lightened one would have set me back another $400-$500 or so....

I also wanted close to stock like city drivability, so thats how I made my decision

 

Had an exedy 8lbs flywheel in my rsx and it makes for a painful drive in city and highway traffic. It gets even worse on hills especially with the anemic torque of the K20 motor. A stock or slightly lighter than stock flywheel would be your best bet in terms of driveability in everyday situations.

 

keep the stocker, resurface it if you have higher mileage...

 

I have a Prostreet flywheel, and noticed that it takes higher revs to get rolling. I couldn't tell a huge difference performance wise, but figured since I was replacing stock I might as well upgrade. Resurface your stocker if its in good shape and if you do go lightened don't go too light.

 

wow i guess i'm the only one but i had an 8.8lb ACT in my old GS-R and absolutley loved it. Made the car way easier to rev-match downshift and got into vtec a lot quicker. i figured it would be the same concept with the evo except with boost.
