Last .1% of performance in a vert, eh?

i went with OEM. not much gain and it does give a lot of NVH unlike other places.

I have AKG 95D in the diff and subframe. Along with RE trans mounts and Bimmerworld motor mounts, it's a very direct driving feel. That being said it does whine. I hate it lol

If your car is bone stock, just go with OE. There's nothing wrong with them.

I have AKG 90A in mine and like them - the shifting feel and powertrain delivery is noticeably, albeit mildly, crisper. I actually don't notice whine much (limited to: freeway speeds, off throttle windows up, radio off) and even then it's minimal (only exhaust upgrade I have is a Dinan muffler. Those who hear more either have different bushings or ultra sensitive ears. I would not tolerate much whine if I heard it, since my car is still a purely street car (albeit modified and limited to weekend use). They do not add any vibration, and do not change the M clunk at all.
I went with poly together with the updated diff bolts thinking that they would also eliminate the possibility of sheering the bolts, by reducing play that much more. But it seems now that upgraded bolts alone are sufficient. 30K and 5 years later, they're still great.

I think the sweet spot would be: OE front bushing, AKG 90A rear bushings.
All in all, I think the tradeoff is probably equal to monoball FCABs, based on the reviews of those - some improved feel (versus actually performance improvement) with a little road going compromise.
