Rear Suspension Movement

[racerb]

Is there anyone making a replacement bushing for the trailing beam on these cars? I ran a Nissan several years ago with a simular rear set-up and the Nismo replacement bushings for that car made a world of difference.

I have the Delrin sitting here just for that reason, but I'm uncertain if it will provide more gains over headaches in terms of bind. Perhaps something of a softer durometer to merely fill in the voids is the approach I may take.

There is a TRD set:

48726-NP900 Rear suspension arm seat inner
48726-NP910 Rear suspension arm seat outer

Each side requires an inner and an outer. They are one of the standard upgrades for the Netz Cup Vitz race cars.

Those would probebly work best since in all likelyhood they are only about an 80 durometer bushing material. A urethane based mount would have enough give to not create so much bind. Or am I seeing them wrong and they are a delrin type material?

Toyota lists them as "Resin", but I would suspect they are either Nylon or Delrin.

You are my hero Scott. LOL, that's all I want. Now who can import these the fastest?

Looking over the part#s though, part #4 looks to be a front control arm bushing.

That's right - The correct part number for the rubber piece for the center of the resin pieces is: 48752-NP900 (Rear suspension support stopper)

I installed the trd rear swaybar on my car on saturday and took it off on Sunday, made my car feel weird and didn't like the added oversteer made it feel sketchy on the freeway

Scott, out of the parts listed, only the two white resin rings are applicable to the torsion beam bushing. 48752-NP900 pertains to a replacement bushing that resides on the shock shaft, just above the dust boot.

OK - I see that now too. I am coming up blank then on the actual rubber piece that goes inside of the two plastic cups. Unless there actually isn't one, and in the installed picture that I posted above, the black piece in the middle of the white is just simply the metal bushing from the middle of the OEM rubber piece.

They're precisely just that- to be mounted on either side of the stock bushing to quell side-to-side(lateral) movements of the torsion beam while leaving articulation of the beam as intended. Someone correct me if I'm wrong but that is how I see it.

You have to love Japanese to English translations too.
