Poly bushes - worth it or not?

I've got a set of poly bushes I'm toying with sticking on the IROC.
However - these aren't fit and forget items, and do require some routine maintenance.
So, my simple question is this:
For a daily driver, that gets me a to b, is it worth sticking them on the IROC or should I just get the car rebushed with OEM replacements?

What are the benefits of polybushing vs. additional maintenance?

What bushings and what additional maintenance?

Just been hearing about them needing 'regular' lubing with silicone.
Just wondering how often that's needed?

Kit in question is the Energy Suspension kit, with Prothane torque arm bushing looking at ordering a Prothane trans. mount, engine mounts.

I run poly throughout. I did swab the torque arm with grease at install several years ago. My sway bar bushings are greaseable, but routine maintenance covers those. Nothing whatsoever with motor or trans mounts. Like camaronewbie says, "Install and ride brutha!"

Re: Poly bushes - worth it or not?

I have done some poly bushings so far they are worth it but talk to me in a few years to see how they hold up compaired to oem. I used sinthetic silicone grease they have not made a noise but I am trying to figure out why my swaybar mounts broke on me

Re: Poly bushes - worth it or not?

I was told when I went to install my A-arm poly bushings that they would be good for a while but then they will start squeaking. Not sure of that yet though since I haven't even gotten to drive the car yet. But I took those things apart and greased the crap out of them before installation.
