Superpro Vs Nismo Bush

[rs88]

Hi people, just want to get your experience or opinions. I've been told that the standard bushes in my front suspension has a crack in it. So .. I've been doing some research on replacing/upgrading the bushes and came across Super pro & Nismo. Other than the differences in materials (superpro is polyu & nismo - rubber), does anyone have an experience in comparing both in terms of feel or performance?

Also, where's the best cheapest place to buy them? I know of Supercheap Auto - is that the cheapest? Time isn't a factor.. I'm only planning to replace them in a couple of months.

poly is harder than rubber, so it won't flex as much. Which can be good as it reduces slight geometry changes under load (heavy cornering). The down side is the bushes absorb less vibration and impact, which means it is transmitted through to the body of the car.

Personally I would use poly on non-load bearing items, like sway bar bushes, but use rubber bushes on most other items. That said, plenty of people have used poly everywhere and seem to be happy with it.

Have a look on some of the USA sites. Energy Suspension make a lot of poly bushes for the G35/350Z for considerably cheaper prices. Whiteline here in Aust, also do a lot of poly bushes for the 350Z. Also look at some nissan/infiniti supplies in USA for factory items as they tend to be a lot cheaper than local dealer prices. Provided you can wait for it to arrive.

Thanks Greg. That's some food for thought. I will look into the Enery Suspension bushes.

Hey,

Have a read of my thread (http://www.skylinesaustralia.com/forums/topic/402404-stillen-sway-bar-problem/), it shouldn't be a problem with other parts where bushings are. But if you are changing sway bars and depending on their thickness, you're best to get the sway bar D bushings for it as well. Finding sway bars with the same thickness size as OE would be much better in the long term to source. Energy Suspension has a good range of products and that's probably where I'm gonna get my sway bar D bushings from. They have a complete kit of bushings for our cars as well, if that's what you're after.
