Poly suspension bushings

Jacques, I have no experince in a Ferrari but a lot of experince with the Polyurathane bushings in Porsche 911's and it is not good for street and OK at best for track driveing. They squeek no matter what lubricant you use eventually, and they bind , and they transfer road vibrations. the only reason we used them in track cars becouse they are cheap way to hold they suspension geomentry. but there are much better ways. I hope you have decided to keep your car, sure sounds like a nice one and the market is a brute now, Fritz

 

Brett at Gran Turismo is rebuilding my 365 and he is also working on a 400 for another guy. He has replaced and or is replacing many of the bushings on these cars. In one of the pictures he posted I could not help but notice a very nice digital cliper that could easily measure bushings. You might try contacting him for assistance.

 

I am in the process of replacing the ones in my 365 GT4/2+2 it is so confusing with the obsolete parts. I am going back to original bushings. The ball joints are what vary in price. it is a good time to be buying though. I have been toying with the idea of mking the sway bar busings out of polyurethane. Maybe reduce a little body roll. I agree with Fritz I can hear the poly a arm bushes in my Pantera when I am on the grass. On pavement the tires and exhaust drown them out. They were already on it when I bought the car. The poly bushes on my four wheeler drive me nuts though.
