For a track toy? Definitely. For a daily driver to occasionally hoon? Not for me. Even my Miata, as small and impractical as it can sometimes be, has to be able to go to the grocery store, out to eat and back and forth to work. No squeaking for me, thank you very much.
I freaking hate squeeky bushings.
Had a TRD away bar upgrade back in the day that came with urethane bushings and a small pack of grease and no matter how well you greased them up within 50 miles they were squeeking like a wooden floor outside your girlfriend's parents room as you sneak past in the night on your first sleep over from the guest room...
The firmness is great, the resistance to ovalling too, the noise.. not so good.
So I brought this up because I end up using urethane because it's not always that easy to get members with replacement rubber. I think of the squeaking as just the sound of a part doing it's job.
I'm actually thinking of trying to pour my own urethane into an old rubber bushing with holes to shore it up. Seems like it might be easier overall than getting spare members, finding compatible bushings, digging out the old rubber, and getting the new ones pressed in, maybe ripping one. I am pleased with urethane motor mount inserts I have used, so maybe something like that would be good for at least some suspension bushings? Just pull the member, drill out some spaces throu the rubber if it doesn't already have that, and pour the urethane in. hmmm.....
