OP, the stock tranny is quite stout and can handle 600-700hp M3/M4s. Unless you're going big turbo and 1000whp I don't see the need to replace it. |

600-700 wtq no problems on the stock clutch, bmw did a good job over building these cars powertrain wise.

Do we have more data on this? How long did the stock clutch last at those higher torque levels? |

Pure was one of the first to do so and they reported that the clutch was able to handle those power levels no problem. Btw the s55 transmission and clutch is shared on the m2, before you start questioning differences.

I'm also currently doing research on solutions myself (New OEM, Spec, Clutchmasters, etc).

But in all seriousness, there are only a few forum posts spotlighting what the clutch can do at a single point in time and it's heavily dependent on the tune as well. A linear torque curve may have prevented slippage while a tune targeting a flat torque curve could see different results. We have no idea how abused these examples are and how long they were driven for at those power levels on the stock clutch - just tough to say. Edit: Attached is another data point where an N55 M2 with 15K miles started getting clutch slip below 600 wtq (580-590):

Just because Pure reported something means we base everything off that? I don't think so.
If according to BMW is correct, 560wtq is already pushing over that 600tq rating. Need more guys pushing these manual setups to get a better feedback. Either way, if and when the clutch goes out it sounds like we will be looking for aftermarket options that will handle more torque and abuse! Any one running an aftermarket setup? |

Called xclutch(left message, Clutch masters recommended the fx400
https://clutchmasters.com/i-30508151...n-disc.html?q= https://www.xclutchusa.com/catalogue XKBM23560-2G Clutch Kit Inc Chromoly Flywheel; 9" Twin Solid Organic Clutch Discs Theres motiv which i haven’t seen reviews of. https://www.motivmotorsport.com/prod...isc-clutch-bmw And Spec, which i see some f80’s are running. https://specclutch.com/applications/bmw-m2/ Seems like they are all around the same price $2300-2500 are organic and hold about 900/1000ftlbs. Didn’t get a firm # from CM but told em I’ll be about 600wheel..Wish there was a cheaper/easier option but seems like these are the choices. Assume all will be slightly chattery and be a lil less street friendly than stock..Anything else to consider? |

Anecdotally, I know a few owners have gone from CM to Spec. Then a few from Spec to XClutch. And a handful of DKM to XClutch. None the other way around.

Anyone glazed a clutch and found first to engage with less smoothness, or like it's a bit more abrupt?
I think maybe I feel it at low speed when I'm 100% more mode. Day to day at 70% settings I don't feel it. |

Yes. Had the CDV removed when I was on the stock clutch. Now I have the E9X slave cylinder with the XClutch kit.
