alfa] Poly Bushings = Noise, Vibration, and Harshness?
I don't think Bob bought this part from me, but in the finest Alfa Digest
tradition, here is my $.02 on the matter anyway .......
In my experience, NVH reaction seems to be variable - i have not had any?
complaints directly back on this part, but my supplier said they had and so
they developed a softer bush to compliment the original offering. on my
site, www.performatek.com both are listed. Interestingly, they did not
change the small end bush, claim it had no real effect on NVH, or more
accurately, the softening of the larger one was sufficient.
As i said, i have not had any direct complaints - however, that does not
mean people were not disappointed. In any case, there seems to be a broad
range of what people find acceptable (or will tolerate). I do know that
some actually like the more direct feel. There may even be a range of what
individual cars feed back. FWIW, the softer bush does have a noticeable
effect in taming NVH issues.
They do last waaaaay better than the OEM pieces.
