STILL no bushings?! - Toyota Yaris Forums

mrbond · 03-12-2009, 01:15 AM

I'm super duper pissed that there STILL isn't a bushing set for the Yaris' suspension! There's some for the xB, but none for the xA or Yaris. Dammit, all these xB's get all the performance attention...and they're not even as aerodynamic or light as the Yaris! You don't see the Netz Cup Series in Japan featuring xB's, do you? No!
But seriously, when is a company going to jump on this? It'd be a good field to go into imo.

turboyaris is making some bushings for the rear torsion beam.

aluminum rear bushing:

I believe they go where I circled

For those that are not in the know (like me)

Applications

Bushings are also used to transfer loads from a fastening to a much larger area in the underlying structure, the object being to reduce the strain on individual fibers within the underlying structure.

In a car or other vehicle's suspension, rubber bushings are used to connect the various moving arms and pivot points to the chassis and other parts of the suspension. In order to minimise vibration, wear, and transmission of noise, they often incorporate flexible material such as rubber or polyurethane. These bushings often take the form of an annular cylinder of flexible material inside a metallic casing or outer tube. They might also feature an internal crush tube which protects the bushing from being crushed by the fixings which hold it onto a threaded spigot. Many different types of bushing designs exist.

Yet, what is the benefit of using these?

Not to thread hijack, but some adjustable shocks without going full coilover would be nice too.

mrbond · 03-12-2009, 01:13 PM

yeah, i knew turboyaris was making those aluminum bushings, so that's cool. but then there's all the rest of the rubber pieces of crap that should be replaced with urethane. i would think that these would have gotten more attention?

ddongbap · 03-12-2009, 04:19 PM

I think SCCA requires the use of stock bushings.

BTW, The point of stiffer bushes is to reduce the slight movement that the stock bushings provide.

the scca only requires that the bushings remain non metal, so going with urethane would be ok

you'd be suprised at the difficulty to get bushings made in urethane, there are only a handful of companys that will do custom urethane bushings for you. I only found one actually that will do a small run of automotive type urethane bushings, not to mention that to make it cost effective, you need to spend a decent amount of money to buy them in a larger quantity. the process first is to replicate them in aluminum or some other material, test fit them, and once you get the proper dimensions, have a negative made so that the company can just pour the urethane in and seal it up.

the outer ring is for overflow purposes.
If I couldn't make that mold, the company would charge me $250 just to make that. Plus, just to pour the urethane is pretty expensive.

If it were just making aluminum bushings, it'd be much easier for me. I am starting with the axle beam bushings, and if they are successful, I will start on some other bushings, probably doing group buys, so my up front cost isn't as high.

2006fronty · 03-12-2009, 05:31 PM

Have you looked into delrin? BTW, What size are those rear bushings?

turboyaris · 03-12-2009, 08:16 PM

hmm delrin... interesting, I hadn't looked at that before, it is a little more cost effective but requires more of my time, it'd be interesting to see how easy it is to machine, I read the machining properties of it, and it doesn't sound too bad. The pieces are made from 3" aluminum rod, I don't remember the exact dimensions, but its something like 1.7" long and 2.6" or so

silver_echo · 03-12-2009, 08:36 PM

if those new bushings would work for my 01, i could try to chip in a little for the machining and the manufacturing run... can't do much, though, as i am poor...

turboyaris · 03-12-2009, 11:46 PM

you would have to verify that the axle beam bushings were the same, doubtful toyota would tell you that, but I ordered a replacement for the Yaris so I could measure and get the dimensions.

YarisSedan · 03-13-2009, 12:26 AM

i been looking for poly bushings as well

the local parts department knows me by name, and car, and has even told me about some of the "do not release" service bulletins, and the manager is willing to look for parts for me while he is at HOME!!!(sweetness)... i will call and check to see if it will match across... i hope so...

mrbond · 03-13-2009, 06:01 PM

Turboyaris, you're making aluminum bushings for the torsion beam, correct? Do you think you'd be able to make aluminum bushings for other suspension components? If you could, I am sure you'd get a lot of business.

CASTREX · 03-13-2009, 06:25 PM

NST already came up with a solid bushing for the engine mount and there was very little interest.

Solid bushings are for hardcore racers...

Urethane bushings on the other side would probably have a good demand. I know I would like some...

And I believe the solid bushing turboyaris showed here is only intended to be the mold for some urethane bushings...

I can make you anything you want

The bushings were originally intended to verify that they would work, and then be produced in either urethane or delrin. However, if you are truly interested, I could make you a special set of bushings in aluminum. p.m. me and we could talk more seriously about it. I feel that urethane or delrin would sell better then aluminum because of racing regulations. Also too though, if you were interested in a full set of aluminum bushings, that would allow me to make them all in aluminum, so I could then make them all in delrin or urethane at a later date.

Word.

silver_echo · 03-13-2009, 08:08 PM

okay so the part numbers are different, so i will have a request for you so that i can figure out if they will fit.... what are the physical dimensions of the bushings in question?
