My stock clutch failed catastrophically on me the other day after my jb3 install (map 6 on 93 octane). I drive my car like I stole it ('07 with a little over 50,000 miles ), so I'm not terribly surprised.

So, I'm replacing my clutch and flywheel with a ClutchMasters FX300 unsprung kevlar clutch and hd pressure plate in addition to blowing my wad on a Dinan lightweight dual mass flywheel for my 335. Throwout and Pilot bearings are being ordered through BMW. I think the setup will work fine, but considering the $ that the components are costing me, I'd appreciate feedback on any problems I may run into, particularly with my clutch selection that can be addressed now before the install.

I'm already running jb3 and dci, dp's along with a slew of other mods to be ordered soon. Anyone have experience w/ windowed/segmented kevlar (particularly unsprung)? Anyone have experience with the Dinan flywheel?

bump. Anyone think ceramic is the way to go?

I don't know about going ceramic, but I can't beleive you would drop $2500 on the Dinan flywheel - all they do is take a stock flywheel and machine it down to loose weight - costs them basically the cost of a stock flywheel and about $200 of machine time. You might want to find a good performance machine shop and have them just lighten your stock flywheel for about a zillion less!

I am not an expert, but I'd leave the flywheel alone. The lighted flywheel is unfortunately weakened too. Be ware of that. If it warps under abuse (you seem to drive the piss out of it anyway), you will be in a world of hurt soon enough.

The Dinan flywheel is just an OEM piece with holes drilled in it. Major rip-off. Stay away from ceramic clutches, they EAT flywheels for lunch. Unsprung wont be as much of an issue with the dual mass flywheel.

The lightened flywheel might take some practice to not stall your engine when starting from a stop...

I'd rather have a modified OEM flywheel than some piece of crap that makes a bunch of noise.

Thanks to some of those that had some constructive comments. However, to those others that feel the need to knock someone's purchase of a performance part, I was simply looking for some input on whether that particular line of kevlar clutch with pressure plate would be sufficient for a car with 400 - 450 lbs of torque. There is really no need to debate the merits of buying the flywheel. Regardless, whether it passes or fails the cost benefit test in your own perspective doesn't matter to me, as it is to ONLY aftermarket dual mass flywheel available right now for the 335i which should contribute to performance gains. Anyway, anyone here even use a kevlar clutch?

The billet flywheel in my car is pretty nice, not exactly a piece FWIW, Modified dual mass flywheels can have some serious issues.

Should work just fine for you.
