I'm looking to install either Prothane or ES bushings on the front sway bar. I like these because they are molded specifically for the stock bracket.

I see ES kit is only 32mm..and stock bar is 34mm (may go with 35mm bar later). What's up with that?
The Prothane bushing is 34mm, but for some reason they show application is for 2003-2004! Bars for ALL years have the same 34mm diameter and the ES bushing is shown to apply to ALL 350Z years as well.

Can anyone here verify that Prothane fits later models?

 

go with oem. i have the complete es front bushing kit and they r noisier than my worn out old bushings. i wanttttt my money backkkkk

 

Don't disagree with your experience on your whole front end. However, I have ES bushings that came with my Hotchkis Sways and they're fine as long as you do as the manufacturer requires and lube them up at the proper mileage.

 

Can't even remember who's bushings I have on my car (Cusco sways) no noise, no issues at all on since 2007. Only replaced them because the OEM bushings were trashed, and I was doing the motor/new rack anyway

Given that the front bushings are so thin, it really doesn't matter what you choose IMHO

Gotta remember this car is old, everything that is out was essentially designed around the original 03. Some things just happen to work for the later cars as well as far as springs having the right rate vs stock, etc. They are popular cars, but not Mustangs, so firms aren't going to have 2 different production runs of parts for items to cater to each split in year when everything physically interchanges.

Most likely just a typo on the Energy site - a 32mm bushing won't fit a 34mm bar obviously. Same goes for Prothane stuff being listed for 03-04 and not later. I would bet they simply have not updated this line item in their catalog/site since the original introduction.

 

^^^^
This!
On the SWAYS you won't get much noise. On Control Arms..end links.. etc...you will.

 

Thanks..that's what I was thinking.
