I read many threads about flywheels and clutches but none of them being compared . from what I know there is fidanza , jwt, competition . no ones compared them ?

fidanza -can't seem to find weight
competition - 10.28 lbs
jwt-12 lbs

all weight are what's shown on there website for the vq30 give or take for the vq35 . can anyone tell me which one is better ? personal experience ?

I have friend that has one on his 02 maxima and it drives great the only problem is when he starts the car it sounds like the starter grinds , plus it chatters . that's one think I don't want to go through if I get one and I'm not sure what brand he has cause he bought it that way .

also I've ready and seen videos on YouTube about the fidanza that the flywheel gears loose on them , and comes apart from the flywheel itself? what's that about ?

any help appreciated . thanks

 

I remember reading a post about the Fidanza having 1 too few or 1 too many teeth. Based on all of my research I'm going with a JWT when I get around to it.

 

heard anything about competition ?

 

nope

 

Fidanza has that +/- tooth thing. The vq35 jwt fly is 15lbs. The reason you get chatter is that the lightweight is a single mass unit which needs a sprung clutch for smoother operation, ur buddy probably has the stock clutch with his lightweight flywheel. The stock unit is dual mass flywheel and that absorbs drivetrain vibrations (including chatter) therefore not needing a sprung clutch.

 

There's no chatter. I have two fidanzas :| If you engage the clutch incorrectly, then it may happen. But I can drive all day and you would think you're riding in an automatic.

 

he has a stage 2 . but anyways that's none of my business . I'm just trying to get some info about the flywheels which is better . I know fidanza is the most popular but I heard a lot of flaws and I haven't heard much about jwt or competition hopefully someone chimes in
