I concur.
If I had the time and money, I would replace my act hdss/prolite with the stock components.

On second thought... nah, my left calf didn't get big for nothing. VROOOM.
Go with itr flywheel. </TD></TR></TABLE>

i used to have that same exact set up in my car, about 3 clutches ago, it was my favorite until now. and the funny thing is i have a stage 2 competition clutch in there right now, and it has almost stock pedal feel, when i had the act in it was considerably harder to push in. but supposedly i have the same clamping force

for competiton.....so far, i have bad luck with cluthes

i've never seen any information showing aluminum flywheels to have a negative effect as opposed to steel/chromoly.</TD></TR></TABLE>

i remember reading that some aluminum flywheels would have issues with the starter...the aluminum was softer than the starter teeth, and the starter would begin to chew up the flywheel teeth..

but i think that is fixed w/ most aluminum units...the fidanza has a chromolly center for this reason...

Aluminum resonates differently than anything else on your rotating assembly, and heats up at a different rate as well.</TD></TR></TABLE>

and please explain how resonation has anything to do with aluminum flywheels and rotating assemblys...i just dont see what youre trying to point out

With personal experience i have found that the 8lb and lighter flywheels are actually a little bit too light with our high revving engines. The flywheel definately revs up faster, but it doesnt carry the momentum into the next gear; it almost seems like the car starts losing more power in the higher RPM range becuse the flywheel is too light to carry any momentum. Next, the 12lb flywheel seemed to be just right, better perfomance over the stock in both the lower and upper RPM range. Call me an idiot, or flame my post, but i am just speaking from personal experience; so i think i am right when i say lighter isnt ALWAYS better.

i also have the street flywheel from act .. and i wouldnt get n e thing else

i dont see how more rotating mass can be better than less...in any situation....

your argument sounds kind of like the one that ppl give about longer gears being better for turbo because "you stay in boost longer"

but this thread seems like its getting some intelligent discussion going..keep it up

u dont know what ur talking about. i just put my stock flywheel back in, and its difference of night and day, and i completly agree with LSracing94

i never said i did....all i have to go by here is physics and common sense...

i know a 7.5lb flywheel is going to be a lot different than an ~18lb or whatever stock flywheel weighs....

seems to me that lighter=faster

but ill let you know this summer after my new flywheel is installed

my buddy has the same thing in his ej1, def quicker revs, good weight for street use, just brake it in right, he didn't now hes going from act to exedy*? my spelling might be off on that

you dont have to break in a flywheel.

well he got a clutch and flywheel, and its recommened to be broken in, maybe your right about just the flyhweel being broken in, my bad

i'd go with the act prolite flywheel. Still very streetable, i can still drive it on the steepest hills.

Dropped90Integra

I bought mine from Autopartswarehouse.com think it came to $607 with shipping for ACT HDSS & Prolite flyhwheel for my GSR.

Might I add that I love the flywheel, I hardly noticed having to shift much faster over stock. When the AC is on thats when its a killer, revs drop like a rocket, but who races with AC on anyway.... for prolite

kuja

Yea i like my act prolite.. I never have any problems, the revs do drop quick IF you let them between shifts. It's just as easy to shift, you just don't have 5 minutes to make the change. Sometimes when ur dead tired in the morning going to work it'll catch you off guard backing out of ur driveway tho ;D

fidanza flywheel here.
9.8 pounds feels way better then stock.
its up to u on wat u want and how much money u have.

My act HDSS slip on me a couple of times and I ended up in the middle of the street with people honking at me. I define slip as in the cluch wouldn't grab so the car just stall. When it did finally grab, the "slip" occured again at 3000 rpm where the needle feel down to 1500 rpm then suddenly, the clutch grabs again and the car jerked. Furthermore, on a hill, the clutch would not grab if I rev to around 3000. It is tricky with the lighten flywheel. Too low of an RPM, stall. I have to get it just right so that the clutch will grab and the car will go forward. It is all about feathering the cluch.

I have jumped to the conclusion that the cluch is glazed. O well. U live n learn.

get a stock clutch

I have a fidanza 7lb that i enjoy.

Sam92Teg

I have the Fidanza 7.5 installed for about 9 months and 7K miles now on my B18A1 with bolt-ons. Took about 10 minutes to get used to it, and that is with a new clutch and 1750 lb pressure plate. I absolutely love it.

I will be pulling the engine and building for performance soon, and do you think I will swap the original flywheel back in? HELL NO!

And as far as revs dropping faster between shifts, it is an added bonus! The revs must drop to match the next longer gear, if they drop faster, you can shift faster. If they drop too fast, you use the throttle with a quick blip to match the gear and vroom your off. Either way you are able to shift faster without harm to any components.

The first thing I noticed was that the engine is much more rev happy and the tires like to spin off the line, but that could be my new clutch also.

itr flywheel FTW

light flywheels sucks ***, try driving uphill on a 8lb flywheel, your car is soo week...i prefer a oem flywheel, and light flyweels DO eliminate torque, as which a oem clutch such as ITR it has no or little affect on the torque.

Vtecfool

Act Prolite flywheel Doesn't affect daily driving whatsoever! If you got any questions pm me.

sorry to be harsh..but youre a complete moron...i drive with a lightweight flywheel and have for a few years now...and they do NOT eliminate torque...i have yet to see the dyno that had ANY torque change due to a flywheel...Flywheels fall under the category of engine response...Some people dislike them because they themselves are ROOKIE drivers that cant keep up with the revs dropping...a heavier flywheel will cause the revs to "hang" for an inexperienced driver to have more time inbetween shifts...learn to drive...remove the trash from your chest of tuner knowledge about flywheels...then come back...

I have an exedy clutch/flywheel in my car, Not the best in traffic but bearable.. I love it.
