Is that the stock dual mass? it looks completely butchered, I dont see ho wthe clutch can grab that

That looks like a lightened stock single mass flywheel...
How much does that weigh??
Stock is about 10kg... I've machined mine down to 7.6kg... Yours looks like it has more metal removed...

I used a lightened M20 flywheel with 325i clutch and starter.

Flywheel after machining and balancing weighed 5.9kg so with the stronger clutch a saving of about 4K over the standard flywheel and clutch.

someone bought be an m42 clutch kit brand new, but I want to go for a Lightweight flywheel. Where can I find some cheaper aluminum flywheels for the stock dual mass setup?

(sorry for hijack)

Who did the work and how lite is it now and how much did it cost?

Not to crap on anyone but that flywheel is dangerous and will come apart and remove one of your feet.

Looks perfect to me!

I have now finished my conversion... epic lol
pros - better throttle response, revs harder from 5k+
cons - idles a bit lumpy, doesnt like revs below 2k although this may be a good thing

highly recomend it

Does the car feel like it has more torque, people say it revs more freely, but that doesnt really make much sense to me?

gtatbrissy · « **Reply #13 on:** October 09, 2009, 01:47:13 AM »

low down u dont feel that much difference but once u are in the power band the car pulls alot stronger if that makes sense...
