Rocking a jdm b18c5 motor and going with a action 6puc clutch but want to upgrade the flywheel while its off anyone recomend a particular brand i was going to use a 7.5lb fidanza or what not cause they are cheap but cheap is not allways best any input at all gets a thanks

 

Check out gripforce clutches on ebay, he has the best pricing on fidanza flywheels.

I got my OE clutch and 8lb fidanza for my D-series for $205 shipped.

 

i love my fidanza 7.5 lb flywheel no complaints at all

 

fidanza is good stuff

 

yeah for the price its offered i think its great to the op i would check out that gripfroce clutches on ebay that EK forever guy mentioned that's a really good deal

 

Just remember, it being a b-series will make it more expensive than my d-series clutch.

I never understood that.

 

well i allready got the clutch i want to get figured out action 6puck just needed a nice flywheel weither it was a j's toda or fidanza thanks for some feedback any other flywheels you guys use or recomend

kaiten flywheel $210 and less. 8.8 pounds. nice quality. Chromoly Steel. strong unit

 

7.5lbs is too light, i would try to stay in the 12-14lb range, there is a reason flywheels weigh 18 lbs..... and it isn't to reduce performance....

 

From what I've heard and experienced, The lighter of the 2 flywheels ( the 7.5 ) sacrifices some of your launch speed, but top end gains are better. The mid-range flywheel ( 12-14lb ) is good for all around, strret and strip. I had a 12 lb on my old SH and was very pleased with it, and it was a Fidanza and yes, they are cheap in price, but not quality. IMO

 

Meh, I've been very happy with my 9lb flywheel.

 

what is your 9lb flywheel

 

the problem with aluminum lywheels is that they tend to be multi-piece units while chromoly units are one piece. look through the archives an you will find stories of alumium flywheels(even fidanza) "exploding" during misshifts. find a good chromoly lywheel such as ACT and exedy(only 2 I can think of off the top of my head).

I had an exedy in my b16a hatch (weighing in at aroud 9 lbs). I will tell you though, anything lighter than 12 lbs will take some serious getting used too (plan on looking like a 1st time driver for the entire first day at least)

 

Anyone have a vid of their car reving up and down with a 7ish lb flywheel?

 

My fidanza is a one piece.



It's one top flywheel companies there are.

 

I have a 12.5 pound ACT streetlight. I like it. It is great for daily driving. I would go with a Prolight if you do more racing.

 

Driveability issues with a lightweight clutch is a complete myth, the lighter it is the easier it is to drive.

I agree, you just have to get used to it. I can't even tell when I shift or engage from a stop anymore.

 

The ACT streetlite is an awesome cheap and well made flywheel. You could buy another one when it comes time to change your clutch they are pretty cheap.

Bullshit, give me a solid explanation then as to why they weigh 18lbs in the first place, if its such a good thing, then why doesn't the factory issue 7lb slabs instead of 18lbs, thats a huge savings in weight and money.

The rod/piston assembly relies on the inertial mass of the flywheel to bring the rod/piston assembly out of TDC, so that the event stroke does not have to work as hard to push the rod/pistons assembly downwards, essentially all you are doing is making the combustion event have to force the piston downward, exerting more stress on them to make the same power, in order to turn the same speed.

Need I also mention that I4 engines are inherently out of balance by design, and an extremely light flywheel would only worsen this fact.

Quick question, if you are deciding to updgrade to lighter flywheel, would you also have to look for a better aftermarket clutch, or would the oem clutch be good enough to take full advantage of the new flywheel?

And just to make sure, aluminim flywheels are more geared to racing, while steel are better suited for daily drivers correct?

 

Ive been using my 9lb flywheel on an exedy oem replacement for 10,000 miles.

Launches hard

Great daily setup for my d.

 

Is your flywheel steel or aluminum?
