got to change my clutch so also looking at super light flywheels.weighing in at 3.5 to 4.5KG.

are they a good ?

is there eney point ?

are they a good mod for the cash.?

this is going on a fast road car with 350+bhp

Well 3.5-4.5kgs is very light indeed... but perhaps TOO LIGHT! If its too light it wont hold any energy when clutching about so you will stall or jump all the time (pain in Traffic) also if too light and spinning at high revs it can get thrown out go through the floor and chop your leg off (Very rare this but has happened)

 

They are very good as this will mean faster acceleration and Higher power outputs (although wont come up on a Dyno)

Best get a custom one done as will be far cheaper (guy on another forum can do flyhweels for around £250)than say an RPS one at £450. All you need is to give them a Stock flywheel then they replicate it, and shave the weight off it while keeping it balanced!

 

RPS ones are around 7kgs and stock is 12kgs (IIRC) i would say around 5-6kgs will be safe but some do have them as light at 3.5-4.5kgs!

 

So all in all... YES great idea if your changing clutch :D

Mine is 4.2 kg and Im very happy with it, it picks up revs so quickly and the acceleration and response improvements is very noticable.

 

I also have it combined with other Lightweigth Drivetrain components - Pulleys and 1piece propshaft, for a total drivetrain saving of 18kg

Where i read 7kgs then i dont know :headvswal

you have put the shits up me now.

i still want a car i can drive in town.mmmmmmmm dont now got me thinking.ho shit.

im not sure on the weight of the one in my old zed, but the garage that fitted it saidf it was extremely light and they build race cars, they also had it skimmed and balanced again as it was scored, must say though and i have had lots of comments about it-it went really really well for the mods it had and boosted very well (although i doubt the boost had anything to do with the flywheel)

 

never had any probs with it though

i think i had said its very rare all that happens!! Just dont go rediculously light and you wont have any problems! As its Rotational weight any reduction will result in a far more responsive engine which is a big + so as your clutch is out i would DEFINATLY recommend putting in a lightened flywheel!Just get one professionally done, don't get the RPS one as its a major RIP OFF!!! (Custom ones can be done far cheaper)

Z1's own brand Flywheels are very well priced too.

got one sorted.clutch and flywheel for £620 with discount from ninga tune factory.clutch is good upto 450bhp.still not shore about the flywheel now.just think it might be to light.

clutch and flywheel now been on for two weeks.am i glad i went for the flywheel...yes...

it is a bit harsh in town but on the open road its just fine.

one thing i have spoted is when i got back from getting the 300 MOTed today was that the short shift was a bit warm.not spoted this befour.

is it just the clutch bedding in ?or do i have a problem.

.......HELP.........
