Helical LSD + Solid Diff Bushings = Which RSFB?

[hyphy1]

LSD + solid diff bushings coming soon...

In the meantime, which rear subframe bushings should I go for to complement the LSD + solid diff bushings? There's so many options!

1) OEM M3 (300)
2) BMW Motorsport (800)
3) Turner Motorsport Solid Delrin/Aluminum (500)
4) AKG Motorsport polyurethane 75D (300)
5) AKG Motorsport polyurethane 95A (300)

Don't know if i'm ready to go solid aluminum as it would invite plenty of NVH.

Might have more luck in the correct forum.

get more NVH with solid diff bushings than with solid subframe bushings. I'd go with stock diff bushings.

He already has MFactory diff bushings, the poll is asking what RSFB he should pair with them

Understand that, my point is that there will be increased NVH now with those, and as a result will end up sacrificing rigidity where it's needed most trying to keep it quiet. At this point either go all solid and live with it, or take out the diff bushings and go softer there.
