A lot of people say their car felt so unstable stock it was virtually unsafe, and that was never my experience. If my car HAD felt like that, they would be absolutely worth it. My car felt great, just a very small amount of squirm on WOT. The squirm is gone but it's definitely somewhat harsher in the rear and while it's a subtle change, you notice after a while of daily driving that it does just beat you up a little more. It's dead quiet (thank God) but less refined. Cobblestone or ground down pavement, expansion joints, speed bumps, etc. really highlight the difference. In other words, it's a lot better at WOT, but it's a little worse at everything else. Most of my driving is not WOT so to me, the $1600 and a minimal but constant decrease in ride quality was not worth it. |

NVH is so subjective. Eg everyone online claims that there was no increase in NVH with monoball tension struts (honeymoon phase?), but I found the increase in harshness unbearable for a daily driver. |

Thanks for the honest review. I've seen so many posts that say "there's literally no increase in NVH" and "they do it on the newer cars" as proof, it's nice to hear an informed opinion. I have the inserts on mine. It improved the squirm under hard acceleration, though it's still there a little. Definitely worth the $ and effort, but I've always wondered if I should do a proper replacement. |

If I were to do it over again, I would go AKG 95A or just do inserts. I think the inserts are a great bang for the buck. |

I had squiggle oem bushings. 3m poly filled them as best I could from underneath and that fixed the majority of the unsettled feeling.
Went with condor delrin RSFB and completely ruined the car lol. I didnt notice any more Noise but I could feel every single pebble/crack etc. for me, It was that moment I knew I had gone to far…. I would try yellow powerflex. Ive redone my e91 subframe and fully filled with 3m urethane so I will see how that feels first. |

How much HP/TQ are you making? Do you have an aftermarket diff? Are the diff bushings stock? Did you code out the E-Diff?
