rackmount bushes, nismo vs poly vs oem

[nicostar]

I tried using the "search" already with different combination of words and could not find any threads on the topic, please forgive me mods.

Can anyone shed some light on the differences between the 3 types and which one lasts the longest and which handles abuse best?

I've not noticed a practical difference, and I've been using OEM in one car and poly in another for years. I went poly when I replaced them due to price and availability not concerns about durability or life.

^^^agreed. Went from oem to superpro, now have nismo. Don't think i'd be able to tell the difference in a blind test...aluminium might be a dufferent story.

Given its not a moving part, wear as such shouldn't be an issue.

Also nismo and oem are rubber..my oem ones looked fine after 16 years when i pulled them out.

Have used rubber, superpro and now moved to aluminium. 

The superpro were fine for the street and had no issues. Aluminium were used to move rack forward but I noticed no difference with feel and noise.
