Update: had the original factory front carrier bushings put back in, left the Turner rear carrier bushing in.
Summary: Vastly less noise now, but louder than stock. The Turner part gives a very solid shift feel, with only slightly more flexiness than when the solid front bushings were also in place. Almost none of that rubbery stock shifter feeling any more, which was the whole point of swapping out the bushing(s) in the first place. I feel the same way DrKevM5 does: great value. Read on for more detail: With both the solid front and rear carrier bushings, I'm pretty certain that I was hearing every noise coming from inside the gearbox. There were different whining noises: one that varied in proportion to road speed, and another that varied in proportion to engine speed. Also, there was a rattle at idle in neutral. This was probably some kind of bearing in the transmission and/or clutch doing its natural thing. You can hear that with the stock setup, but it's very subtle. And each shift sounded like someone smacking two giant billiard balls together. That level of noise would be perfectly OK in a track-only car. In fact, hearing all that extra gear noise would probably give very useful on-track feedback about speeds in gears, transmission health, and all that good stuff. But this is my DD, and I don't want a noise floor that high just driving around town. Wimpy. I know. With only the Turner bushing (back on topic finally) the noise level is still noticeably higher than stock. But it's not unacceptable IMHO. I had a Dinan mid-pipe installed at the same time as the front and rear shifter bushings, and I couldn't hear much difference in the exhaust note because of all the gear whine etc. Now I can hear that there is a definite improvement in exhaust tone with the Dinan mid-pipe. All the gear whine is still there, but far more subdued than when the solid front bushings were in place. IMHO it's acceptable now even though it's noisier than stock. I'll keep the stock rear bushing and bracket just in case I change my mind later. Shift action is still quite a bit noisier than stock because of that louder "clack" on each shift. The net effect of the Turner rear shifter bushing is a more solid shift feel at the expense of additional noise. But I recommend keeping the stock front shifter carrier bushings if your M2 is your daily driver.

https://www.turnermotorsport.com/p-3...r-arm-bushing/ It's a 70A rubber instead of powerflex's 90a so maybe it'll be soft enough to eliminate the crazy increase in noise, but hard enough to porivde an even better shift feel. |

I was going to go with the Turner rear bushing, but decided to replace the whole shifter assembly with a Autosolutions Short Shifter. $80 for one bushing vs $450 for a whole new shifter, which will tighten up the whole shifter assembly. The new shifter assembly consists of 2 Poly bushings with brass inserts that connect the front of the shifter arm to the transmission (unsprung weight).It also has a new shifter and bushing in the shifter arm. The rear bushing is reinstalled (sprung weight), which is attached to underside of the body.

I finally got around to installing the Turner rear bushing (bought it a year ago). It took some work to get access but not too bad. You may be able to get away with unbolting just the heat shield and bending it out of the way. I chose to remove the large panel under the gearbox too. The two 8mm bolts holding the bushing require a 12 point socket but I was able to use a 6 point with no problem. They were not too tight (I think they're aluminum alloy).
With that, the shifts are much crisper, with none of the rubbery feeling. If you compared the old to the new bushing, you'll see why. The old bushing is made of a very soft rubber that seems designed to reduce noise more than serve as a mounting point. When in neutral, there is noise that sounds like marbles rolling around inside the gear box, but that goes away when everything's warmed up. During shifting, there is a noticeable click-clack that lets you know there is now a solid connection between the shifter and the gearbox. You can actually feel the gears sliding into place. With this and the Ultimate Clutch Pedal, I'm now in shifter heaven. I enjoy it so much that I beg for stop and go traffic. For about 90 bucks, it's the biggest bang for the buck. Do it! |

So I'm not clear on what this parts does. Reduce side to side play or front to back play or none of the above?
The gearbox is noisier ? I sometimes think my MT is really great other times a bit rubbery! Bolt action gated R8 style would be sweet |

Odd. After sitting for a month, the gearshift felt better than I remembered it. Noting that mine had the clutch replaced under warranty as it wasn't releasing properly, it has always felt better if I don't force it - both for a single shift, and for some time afterwards. The parts are common across the M2/3/4, while the bushings used are used across most of the range.

I have it installed since the summer. I personally love it. I have it with a M perf shifter (sort of a rip off but I bought it second hand so it was ok). Definitely a noticeable difference and personally and it is a lot less "rubbery".
In terms of the installation it was very easy like the TLG video mentioned. The hardest part of the install was removing the heat shield turkey tray thing. And it wasn't even that hard just bend it so it slides out and then bend it back when you install. Took me about 30 minutes to install not very hard at all! |

Turner bushing: I’ve followed what the above video says on sliding that aluminum head shield into the rear HS. Shifting the aluminum bracket to the side. Works. Everything was a breeze except putting that passenger side torx bolt that’s holding the bushing. Tough getting it in for some reason coz it wasn’t aligning right for some reason. THAT took a while for me coz I wanted to be certain it’s aligned and not cross threaded. Of course the fact that it's partly being covered by the driveshaft didn't help. I didn't want to end up removing the driveshaft to fix a crossed thread.
Started the car, reversed out of my garage and I can feel the difference right away. Ka-tzAK ka-tzAK. It sounds and feels firmer that’s for sure. It’s definitely less rubbery. I’d say it’s at least 20-30% better. Definitely worth the cost & effort IMO. I wonder if that PU would eventually loosen and become rattle-ly. If you’re the type that like a silent shifting though then this might not be for you. You can hear the shifting more. Like I said ka-tzAK! Last edited by vrooooom; 12-11-2021 at 03:45 AM.. |

I had to bring my car into my shop as had some rattling etc. with my EL mid pipe so while there I had them install the Turner rear shifter bushing. Initial impression is very good with less slop and the 1st to 2nd shift which is never consistent is just better so that is a surprise. And I concur with Vroooom it has that "ka-tzak sound lol.. AutoSolutions shifter is on the future mod list so the combo of the 2 should add to the overall experience.
