A couple of recent things have brought out the idea of the underside bushings: 1. seeing what the engine mounts looked like. They were punished something awful. 2. Seeing what happened on track with my friend's 996 GT3. My friend with the GT3 has been having some failures on track---the most recent being a broken rear axle at Turn 2 at Sonoma. That experience led him to have an entire round of rejuvenating done to the car. It was VERY expensive, but the axle demonstrated in very clear terms that stuff simply needs to be replaced on a regular cycle when used this hard---even if nothing appears to be wrong.
So I'm trying to stay ahead of parts failing. In the world of cars, I find it better to be proactive, and stay ahead of problems, than be reactive and deal with failures as they happen......because dealing with failures as they happen usually means having parts fail on track. My friend went from being reactive to super proactive. Of course, it depends on how hard you drive and how often and what the car is subjected to, but there are general conventions that one can follow when doing preventive maintenance.
We look at the stock underside bushings all the time, and they seem to be holding up, but now I'm thinking they've definitely lived a full life and maybe I should consider the next step.

interesting, thanks. you definitely seem like the type of person that does in-depth research about parts to draw logical conclusions. i would be interested to know which direction you go with what bushings and why.
i'm likely going to head to MRF engineering when i decide to get mine, mostly because it seems like he has a lot of experience and seems to be very competent in this area.
hopefully i'll bump into you at the track someday, i'd be happy to buy you lunch, check out your car, and pick your brain a bit more.
