I take everyone opinion w/ a grain of salt, so having said that....ive "heard" people mention that using poly bushing for normal driving will wear out just as quickly as rubber since normal roads are much rougher than say a track. As long as the poly doesn't squeek (lube liberally) and I'm still going to have to replace them on the same intervals as the rubber versions, I'd rather have the firmer ride. My X is already pretty stiff as is, and as far as I know, its still all stock pieces @ 97k.
