@robc1976 so if I understand correctly, you felt the powerflex subframe bushings deflect less than the m3, yet have less NVH ? Is there less thumping noise from the LSD with the powerflex bushings vs the m3?

Hmm. Im 6mt so idk if that could make it noiser or more vibration. But maybe i should just go with poly bushings from the beginning.

I bought new rear sub frame bushings from the main stealer, front and rear positions, but am not installing them now so have put up for sale. They are brand new in their boxes...

How are the powerflex bushings holding up through the winters? Or do you not drive the car through the winter?

Just wondering, because I read someone's comment about longevity, and if I have to keep replacing them because I do drive through the winter, then I don't think they're the right ones to go with.
