So I'm thinking it's time to replace bushing in my 91.
Currently all the bushings look like original rubber bushings. I have no documentation that they have ever been replaced. There are lots of little clunks and vagueness in turns that make me think they are performing a lot less than off the showroom floor quality now that the car is at 175k.
Right now I am in the process of replacing the center bearing and guibo. So while I'm down there I was thinking of starting with the transmission bushings. Next I intend on tackling the rear subframe, control arm, and final drive bushings. Then I'll work my way up to the front. Down the road I intend on putting HR Cab springs, Koni orange struts, and x brace.
My question is rubber or poly? Currently the car suspension is bone stock. I don't intend on ever tracking the car. I do want it to be much more responsive than it is currently, but I'm guessing either will probably help with that. I've been eyeing the Garagtastic 80A autox/street poly bushings specifically.
I have read that poly will last longer and that is appealing, but that it transmits more noise and vibration. Everything I read is pretty vague on what that means exactly though. Something in me thinks that how bad could the noise be in comparison to having some canvas over my head as the only thing keeping wind and road noise out. It isn't as if the convertible is a quiet leader anyway. Is poly grossly louder? Is it uncomfortably vibration prone for a daily driven street car? Is is possible or advisable to mix rubber and poly in different locations, or just go one way or the other? Just so confused.
