Thanks a million for this post, I had been trying to figure out what to do about a short shifter. All the other options I had seen seemed inadequate. I put my order in today.
For anyone else thinking about this shifter, Ronald builds shifters in batches, and he says he's going to be starting a run of M2 shifters early to middle of next week. It's prime time for ordering one. |

You can't "speed shift" these new BMWs without the shifter gate blocking such action or without possible damaging the synchronizers.
Other than feel, I don't see the need for a short shifter. It's not race car with a "dog box", it was made with daily driving in mind, which has some play built in. There's a slightly lighter flywheel for the M2 over the standard manual BMWs but other than that, it's the same exact gearbox. OP, thanks for the feedback, regardless. |

After a lot of discussion with Ron I went for 10mm shorter and 20% less throw. BMW made a "proper" short shift kit for the E9x range with replacement carrier, bearings and a reduced throw shift arm and linkage - it transformed the my 335i IMO that's why I wanted one for the M2C which has a very similar 'box to my old 335i. It also got rid of that sometimes stodgy feel, made it very clickety-clack feel with all the rubber squidge removed, very nice. See BMW short shift kit here - why they don't make one for newer models I don;t know? Last edited by doughboy; 06-15-2019 at 07:19 AM.. |

I noticed a few folks mentioning a noisy sound coming from the AS SSK with stock knob, but went away when going with a Raceseng, for example. Anyone running M Performance Knob w/ AS SSK with no / minimal sound issues?

The increased noise is due to parts of the short shifter, as well as any replaced bushings, which are more firm. A heavier, larger shift knob, like some of the ones from Raceseng, can help to reduce the noise, but will also numb the feel a bit.
For me, I welcome the 'noise'. It's not a random noise; it's more communication with the car, and gives you more feedback on what's going on with the engine/tranny. I prefer the OEM knob to the M-Performance one; mainly because I'm an overhand/partial side-hand shifter. |

i think we are talking about different noises.
I mean a pretty intrusive whirring / ringing noise that is primary shaft speed, the mperformance shift knob amplified this sound. A bit like an electric drill kind of noise. Enough for passengers to ask what it is unless you turn the music up. not good. The short shift kit naturally makes the shift MORE notchy and stiff which is both good and bad. A heavy shift knob helps a lot to smooth out the notches without numbing the tight mechanical feel, it doesnt add any flex to the shift just mass and momentum. it also damps the high frequency whirring / ringing noise that I was getting. |

I have the stock shifter and very minimal noise after 200 miles. A few more thoughts here: https://www.bimmerpost.com/forums/sh...php?p=25642152

i.e. a -20% throw reduction will increase shift effort by +20% If you also have a reduced height this decreases the effective throw and further increases effort. I went for -20% throw and -10mm height, which works out about -23% throw overall. But as I now have a Raceseng shift knob, that is a little taller than OE, so I'm about back at OE shift height. Also, re armrest clash, that is more about your shoulder height as to whether your elbow hits the armrest, a lower shift knob will lower your hand and forearm a little but not your shoulder and elbow of course. |

I did try a couple of Raceseng knobs. IMO, their weighted shift knobs are too heavy; they numb the feel. I have their circuit series as well (lighter), and it's too tall. It also just doesn't feel as crisp and direct as the OEM knob. I'm guessing it's because of the threaded adapter you have to use, but I'm not sure. It's a shame; I really like their knobs, and they just came out with some fantastic leather knobs. As for the armrest, you should have no issues with it, assuming you have no issues with it currently. |

Sort of a related question:
For those of you doing this on a S55 M2C and changing shift knobs-- isn't the boot and the knob one piece? If so, how did you deal with that to change knobs? I'm going to do this after my 1200 break-in, but I'm looking at a ZDV knob to replace the OEM one. Thanks-- R. |

There's not an easy way to deal with this. You just have to fiddle with it to separate the boot from the knob. It's glued on, and there is a plastic ring you have to dislodge. You can pry it off, heat it, break it, etc. Just be slow and meticulous. |

And one last stupid question: I'm assuming that the S55 M2C OEM knob is NOT the same as the weighted ZHP one? They look pretty similar in pictures I've seen. Again, Thanks. R. |

It is definitely doable, and has been done by many
I could be wrong, but I believe it IS the same as the weighted ZHP knob. I had a ZHP shift knob before, and to my (terrible) memory, it looks/feels about the same. It seems BMW listened after all the complaining about the cheap, terrible E9X M3 shift knob. |
