Just wondering how important are the bushes on a car, I Know a few of mine need changing but wanted to know more about it, its important for handling that I know but has got anything to do with ride and comfort of the car? Would worn out bushes cause sudden banging from the suspension when it hits potholes etc? My absorbers and springs are fine. Also the question about poly bushes or standard ones is it worth going for poly bushes and are the hard to fit?
