My car's Tremec has no-lift shift. To be honest, I don't use it. I drive too many different manual cars (HPDE instructor) and don't want to develop that no-lift habit. I really, really loved the G87 M2, though. And I'm just picking a bit on the shifter. It could be my impression, but the M240i ZF8 appeared to have more low end pep than the M2 6-speed. I wonder if that is what the reviewers were whining about the lack of power in the manual. |

It is a simple downshift auto blip - actually, less of a blip and more of a bump of the RPM up to where it should be in the lower gear. Works very well, but still I'd have it off as I can't control my foot - it always blips on it's own. I honestly don't think there is anything wrong with the clutch - it's fine and easy to modulate. I had to maneuver out of a tight parking spot and parking lot right off the bat and was instantly comfortable and smooth. The clutch and shifter are very, very smooth and light. Just the throws are long and rubbery/imprecise (hard to describe). |

my gt3 has the no lift shift as well and i hardly use it. but sometimes when you want acceleration its nice as there is no delay between the 1-2 shift at redline. almost makes it pdk like. it would be more beneficial to the m2 due to the turbo lag between shifts with spirited driving.

*in my experience, which goes back to the e46. I will note that BMW engines "float the RPMs" a beat longer than, say, super high compression Japanese 4 cylinder engines. Perhaps the long throw is there to delay your upshift action, giving the RPMs time to drop into the sweet sport for the higher gear. This difference in shift timing KICKED MY ASS the first time I drove a BMW. Coming from a 4 banger, I was trying to upshift way too fast and not waiting for the RPMs to spin down, leading to bucking. BMW motors do NOT like to be hurried. This is just my pet theory, I've never done actual research or anything. |

I think BMW could do themselves a huge favor with minimal cost and at least just weight the shift knob better. At one point I tried swapping out the standard knob in the F87 for the weighted (and shorter) ZHP knob and it made a big difference in shift feel.
At the end of the day, I guess you get used to BMW shifters. There are definitely better and there are definitely worse. It’s unfortunate they don’t put more development effort into it but it’s not bad enough to ruin the driving experience. |

I understand this is the same transmission as in the F8x. With the same "long and rubbery" throws. Is that not the case?
Fewer people complained then. And for those who did, there is always a SSK. A manual transmission won't be as fast, won't be as convenient in traffic, blah blah blah. You want one because you crave the extra layer of involvement, and are willing to put the up with the extra work. If you are considering the manual, just get it, stop complaining. It isn't different than the other million of BMW manual transmissions from the past. Edit: If you are in the area and on the fence, I offer anyone to test drive my car with the Auto Solutions SSK.

The only other manual BMW I drive regularly is a SpecE30 race car - which has it's unique characteristics as well. Driven one E36 and a few E46 on track, and E46 seems to be the best manuals from memory. Don't think I had to give that transmission an extra thought. G87 made me think about each shift. Not that it is bad - just not seamless. |

Rogue Engineering, UUC, Auto Solutions are just some who make SSK's for many of the BMW generations. I have experienced UUC and Auto Solutions in the F8x generation. The Auto Solutions is the better one by far. They don't offer an off the shelf common solution, they engineer each one of them for your specific usage. - They alter the geometry of the shifter linkage - They retain the main carrier arm (very solid in these cars) - Different fulcrum (pivot) mechanism - Replaces some of the bushings with increased hardness ones When you talk to Ron @ Auto Solutions, he asks you about the typical usage of the car (street vs. track vs. drag), whether or not you want to retain the stock knob, whether you want to retain the stock height of the knob, the percentage of shift throw reduction, etc. Based on this mini-interview, he recommends a specific configuration (which you are free to alter any way you want). Then he makes it for you. And not for a ton of money, it's just a little bit more than the other ones. My results were a smooth yet much more precise engagement feel, reduced throw, stock appearance. Huge difference.

I'm now leaning back to the manual. Which is great given how many of the HEA cars are manuals, with luck I'll land one soon. |

MilesPerHr Review
Hadn't heard of this guy before but he seems to have about 1/2M subs. - feels too much like an M4 to drive now. very predictable/stable. Old M2 felt like its on tossable/exciting thing that was separate from the F82. At the end he says he likes the new M2 and it will appeal to more people now with the ride and refinement, but he loved the old m2 comp more. - He does the 4th gear low rpm test like throttle house. but punching it from 3000rpm. says the car takes a long time to build boost and get moving. at 17:00

That last fact is what has me so weirded out about BMW's claims, the IND dyno run, etc etc. IND still hasn't commented on how the car's power curve shifted 500RPM on the second run. I believe the car makes differing amounts of boost in different gears. |

If done on purpose, that would be... unprecedented? I'd normally be skeptical, but IND is reputable. So I'm with you, I would like more hard data. It's possible it's a software bug, not unusual for a first-year model. Especially since it doesn't seem everyone sees this behavior.

Lots of high horsepower configurations limit boost in lower gears - Ferrari does this extensively. I know Mercedes has been doing it for a long time since their V12biturbo engine. I'm not claiming this is the case, but with everything we've seen, something funny is going on with the numbers because they do not align with what I see on my boost gauge. Even in Sport Plus it's not making any boost until 3k. |
