Shifter Bushes - Poly vs OE Rubber
As the title suggests I'm going to replace my oval shifter bushes and want to hear people's experience of if the polyurethane ones transmit any NVH.
I've replaced shifter bushes with OE in the past on my E46 6-speed and liked how that felt but there's no difference in price for these on the E92 so am curious if the shifting feels better with poly. OE Parts - 25.11.7.507.695 Polyurethane part - PFF5-4631 I've got new OE plastic surround and rear mounting bush (25.11.1.220.600 & 25.11.1.222.015) and might also replace the rod at the front 25.11.7.580.281 TIA 2012 335i manual |

I recently replaced mine (as described here https://www.e90post.com/forums/showp...ostcount=24254) with the Rogue Engineering delrin bushings.
I refreshed everything else in the shifter at the same time + replaced the lever with the SSK part + upgraded transmission mounts to the Rogue ones; so it's tough for me to isolate exactly which parts affected the behavior. Overall, I would say NVH is negligible. I might notice a tad more exhaust note, but I was assuming that's the transmission mounts. I will say, though, that shifting is much notchier. I haven't decided if I like it or not. |

Most gears are fine but reverse is difficult to engage occasionally too. My hopes is that new bushes and mounts will keep the selector forks in their proper alignment and make it easier to get into every gear. (i've deleted the CDV too btw) I'm thinking of getting poly for those linkage bushes |

The shift effort is overall higher (makes sense with the shorter shift lever). The resulting perception is that it's not sliding into gear as easily, but after the MTF flush and driving a few miles, I'm thinking that's just my impression and I might just need to get used to it. |
