Aluminum Flywheel for E89 Z3 35i? Where to find and experiences?
Hi!
I find the clutch / flywheel feel on this car to be the main detractor from a more direct feeling sports car feel. I want to replace the dual mass boat anchor with lightweight clutch and flywheel assembly. I'm surprised there does not seem to be anything out there for this car (I have a 2009 SDrive35i).
Anyone know of a good one? Has anyone tried tried it? Thanks!

Have you already had the CDV removed?
If not it might be an idea to get this removed first to see if you find it any better.
Oh, your car is a Z4 by the way.

I'm sure there's loads out there. The tuning market for these engines is MASSIVE.
Just do a good search for manual n54 engine hop up parts. It doesnt have the be e89 specific...
Just be sure when you go smf you also get a compatible spring clutch disk in order to make it work.
Be prepared for some diesel like noises though.

TBH it's not the flywheel... it's the turbos. Turbo engines and direct response don't exactly go hand in hand.

Nope...it's not the turbos. I've had turbo cars for years and even when mated to a tiny four banger there's a difference between a shift and clutch feel that is direct and one that is overly insulated.

That's what I thought but still slim pickings and there does seem to be variations...hence my hope of finding someone here with a Z4 twin turbo six who has done this modification.GuidoK wrote: ↑Mon May 22, 2017 6:26 pm I'm sure there's loads out there.

I've never read that anyone did this on the e89 here.
But I find multiple suppliers on smf's or spring clutches when I do a search so it cant be that hard. You might have to shop in the US.
What variations do you mean? N54 is N54, and I think they all have the same gearbox. e89 and 135i for sure.
Do some part research in the ETK

It can just be removed and both ends reconnected then bled.

The CDV delet won't give you what you I don't think. Try it it's a free mod! I have a UUC aluminium flywheel and SMC it really let's the engine rev freely but I haven't driven with it yet. As I am in the middle of a project.

Were the parts expensive? You have already fit them? Was in a PITA or pretty straightforward? What's the weight of the flywheel?Machine monkey wrote: ↑Mon May 22, 2017 7:42 pmThe CDV delet won't give you what you I don't think. Try it it's a free mod!

It was a couple of years ago that I had it removed.
From what I remember though there is a panel under the engine that gives access to the CDV and a bleed nipple there also.

I brought mine off hear it was second hand but not fitted. Not sure on the weight as it wasn't a big issue for me. I just needed rid of the soggy feeling DMC and mine was on the way out. And I also needed something a bit stronger.Valor1 wrote: ↑Mon May 22, 2017 7:51 pmWere the parts expensive? You have already fit them? Was in a PITA or pretty straightforward?

Not the easiest of jobs, gearbox needs to come out and some of the bolts are a bit tricky to get to. It is about a days work and I wouldn't fancy doing without a lift.

Thanks everyone for the info. Seems accessing the bleed screw is a PITA! As for fitting the flywheel, perhaps that's why they put it up for sale? Too daunting an undertaking for themMachine monkey wrote: ↑Mon May 22, 2017 8:21 pmI brought mine off hear it was second hand but not fitted. Not sure on the weight as it wasn't a big issue for me.
