NSX Urethane Suspension Bushing Kit in Development
- Thread starter chussey
- Start date
They are surprisingly flexible yet strong. Only concern is squeaking noises due to grease running out, at idle you'll hear them a bit after a few years unless you re-grease them.
I supplied them with the car and mounts for development, so my price is lower than most :wink:

Well is there price published for general public?
Not that I'm aware of.
You'll have to contact Dee Engineering or Prothane and ask. They just finished developing the parts a few days ago, don't know if they have them available for sale yet.
I decided to go in a different direction rather than oem rubber or polyurethane.
I used Delrin in the front control arm assemblies.

It's also much harder than poly bushings, at least Energy Suspension red bushings and i suspect the above mentioned are quite more flexible than Delrin.
Correct, nothing new about them at all. In fact most of the offroad race teams use them because of the durability and self lubrication properties.
If they can withstand the torture of off road racing, anything I throw at them they will laugh at, and I beat my car up far more than 99% of those here.
They are pressed in. There is no point using adhesive when your pressing something in since all the adhesive would be pressed out during the process if done correctly anyway.

Absolutely, polyurethane bushing are much more pliable (flexible) than Delrin.
Which is exactly why I didn't use polyurethane. I don't want any flexing in my suspension control arms that causes deflection alignment changes under load on the race track.
Had my NSX aligned today after installing them for racing this Saturday, what a difference on the drive home, love how it feels now.
Much tighter front end wise and steers like a go-cart.

That's true, Delrin is quite resistant to almost everything (it's not unlike Teflon) but what about comfort, that means now you can feel every imperfection of the road, something your back might remind you after a long drive 
Didn't seem to change that, but if it did on long drives, I would make the adjustment on my shock compression settings.

This is awesome!! We have needed a good non-solid option for these cars forever.
Huge props to everyone involved in this project.
How did you get the delrin bushings, did you custom make them?

Maybe some thoughts here on my issue?
Would be interesting to have the shock bushings made in Poly as well ...

Not really since your front assembles have to be removed to put them in.
It was something I did for my own NSX.
