FN2 Flywheel upgrade

So here I am with a question about buy or not to buy kkkk

What do you think about changing the oem flywheel ?

I think oem weights 4.8kg and I'm looking for a competition clutch with 3.8kg.

Worth changing for a lighter one or not ?

Cheers

Correct me if I'm wrong but I've been told in the past that the engine will spin up slightly quicker with a lightened flywheel but torque figure at the wheels will drop.

Ive got the clockwise one, and it does spin up a lot quicker.. but then also the revs drop off quicker too, so takes some getting use to.

If the car is used on the road rather than on the track, don't do it. The flywheel is pretty light as it is, and reducing the weight will just make the car harder to drive at lower speeds, especially when cold.

A lighter flywheel also needs more gas when cruising (lack of mass).

Accelerating is more fun tho.

I have just had a competition flywheel installed and it weighs 3.8kg. The accererlation is mental ! Straight pass vtec crossover and over 8k then repeat on next gear lol


Peeps who have sat in my car, said when I give it some throttle,, its like being in a aeroplane when it takes off. You get pushed back lol


I have not stalled it once. Also I've started it up in cold and been in bad xmas shopping traffic. All the way back from Euro spec as well for the first time. Does not feel much different to the OEM flywheel. In fact it feels better. And the car rolls at 4 - 5 mph on its own anyway so its not a problem. Biting point hasn't really changed much. I highly recommend the competition flywheel 3.8kg

Same with mfactory's lightened flywheel, not as light as 3.8kg but not far off.

Revs up very quickly and no / minimal loss of torque across the revs (still getting 150lbft) below vtec.

Only downside is traffic uphill, absolute nightmare in any car but with a lightened flywheel it's painful when trying to be mechanically sympathetic.

if the box is coming off for a new clutch or some other work its well worth chucking a lighter fly on, but to go to all the effort for only the fly is pointless in my opinion.

its a great and well worth while mod if you have the chance to chuck one on.

I got a lightened flywheel fitted to mine, Love how it drives with it

Farqui has had a go and i'm sure he can give his opinion

Light flywheel is not good for daily driving in my opinion. In the city you need to change gears very often and push acceleration pedal much more. Light flywheel = less torque. Stock flywheel is light enought. IMO not worth to change.
