Approx $150 from the USA for just the flywheel. Although I'm sure customs won't be too much

Just looked back at my quote from the UK Dist:
Spec stage 2+ = £633.58 Inc Delivery and VAT Aluminium FW = £496.25 Inc Delivery and VAT Fitting of both £250 Inc.. I'll send the guy a message about: 3 Steel FWs 2 Spec Stage 2+ clutches See what he can do...

On the positive side I never had it slip or feel like it wouldn't hold, but I'm not sure I would buy it again. I would be interested to hear your experience if you go down the Spec stage 2+ route. __________________ 6MT | PROcede v3 | AR DPs | Helix FMIC | Forge DV | Quaife LSD | AP Racing BBK | Hartge ARBs | M3 suspension | Öhlins Road & Track | HPF Stg 2 clutch | Bastuck exhaust | P3 Gauge |

There must be cheaper options for a simple solid steel flywheel?? |

I then had it replaced by the HPF Feramic stage 1, after having driven Lars' car with the stage 2. In the end I think though that the engagement between stage 1 and 2 is not that much different. It's noticeably stiffer than with the CM clutch, let alone the OEM one. The HPF works fine, no slippage at all, just the engagement is not very smooth and there's still quite a bit of judder depending on how I engage the clutch. The issue I'm having now is not the clutch but rather the flywheel. When installing the CM FX300, a new flywheel was also installed. When installing the HPF clutch, the flywheel was replaced again as apparently the (second) original one already had lots of play in it. In the end it's rather obvious that the original dual mass flywheel is not up to cope with the massive torque that my car (and idnan's) are putting out. That's at least in my opinion the reason why we get these vibrations from the drivetrain when going WOT, and why I'm now consistently getting misfires in the high rev range which are caused by the knock sensors that confuse the massive drivetrain vibrations with a knock event. A temporary bypass will probably be to deactivate the knock detection (COBB can do that), but in the end it seems I'll have to go with a single mass flywheel. As the aluminium ones are quite noisy, I'm currently also leaning towards the Spec steel flywheel. Ideally however I'd like to combine that with my current HPF clutch as I don't want to buy still another clutch (I'd really like to spend my hard-earned money on other things than clutches...). So if you're doing a group buy on Spec clutches and flywheels I'm potentially interested as well. Alpina_B3_Lux

Do you know how heavy the Aluminium FW is? I could also be interested in that.

Re the 'noise' issue, this is surely just gearbox shaft rattles ususally masked at idle by the DMF, a slight raise in idle speed should sort that out, to say 800/900. What other issues / problems do you know about with the solid Ally flywheels? Mike Spec data is 22lbs steel and 14lbs ally. Last edited by doughboy; 03-06-2013 at 03:43 AM.. |

I'm in the same boat and I've put the question to both Spec and HPF on the other forum about using their products together. With such a new clutch in mine I have no urge to change it. I'm getting these issues on just pump gas, I've not even fitted my meth kit back on yet And it is highly interesting that your first flywheel had so much play in it as I had exactly the same issue with my replacement one at 10k. Even such that LUK saw fit to give me a refund as I had already bought a replacement one. I was doubtful that mine had failed so quickly but I suppose at these power levels anything is possible. |

I'm hopefully going to get INPA working so will look into raising the idle speed if we all go down this route. |

I may still go Ali fw.
Seems to give a noticeable improvement in responsiveness and makes the car lighter on its feet.. I do very little sitting still idling - the time when you hear chatter. By dipping the clutch the rattle goes away anyway. There is still chatter on the steel SMFW but not so bad.. Here is a car with spec stage 3 and Ali fw. I contacted him for feedback he has put 40,000 miles on this setup and loves it - I think he also has RBs http://youtu.be/9bP_H28U_2Q

+1 Phil,
I like the increased engine response given by the lighter flywheel, i'm sure it changes the way the car feels quite significantly when driven. Almost looking forward to it really (not looking forward to paying for it though..) Last edited by doughboy; 03-06-2013 at 05:26 AM.. |

I know it may be a silly comment. And I am unsure of pricing.
But why not upgrade the clutch to an oem one considering it has lasted this long? Phil are you going to be upgrading your turbos or anything or sticking with your current setup? If you aren't going more powerful, maybe a brand new stock clutch could hold for another 50k? |

A slight contradiction there, you can't upgrade back to where you started from! Throwing good money at a new clutch you know will fail is probably not good sense. Plus labour of course.
The OE clutches aren't cheap, and mine has failed at 42k, but about 25k tuned. |

Whoops sorry that was a mistake.
Carry on discussing. I have no idea how a stock clutch competes price wise.. I will go back and hide behind the screen now |

So total $1418 @ 0.66£/$ = £935 even before shipping and duty etc. So £1102 from a UK supplier is alright in my book, maybe with more discount to come..... |

Not to mention someone to speak to with any issues...
For £250 I'd probably get them to fit mine..

I've had a tech reply from David Norton at specclutch.
He said he personally runs the ally fw in a 335is and it gave the biggesr dyno increase of any single application they have tested. Plus 17.2 rwhp apparently.... |

Didn't expect a power increase - bonus! I guess it will make a big difference to transmission losses due to the lower inertia required to turn a much lighter FW.
I might get these fitted at the same time: http://www.e90post.com/forums/showthread.php?t=810291
