Polyurethane Bushing Kits performance???

[string]

how can you say that string?

Poly has way better properties then OEM rubber.

I don't know anything about the materials except for ES's advertising ploy, but experience has shown me (es masterkit) that poly bushings wear badly. The design allows rotation in only one axis, any force attempting to move the bar in other directions will lead to wear. Not many bushings in the DA/DC suspension which only rotate in one axis. Eventually the tight fitting hole in the centre of the poly bushing will oval and your performance will spiral downward.

Exactly locating the suspension members is critical to performance. OEM bushings, whilst arguable not as durable, are designed to allow and accept the correct suspension movement and will maintain geometry for longer.

If you're bushings are so shot that you can wobble the control arms around, and you only plan to have the car for a little while longer, then it's a cheap fix. If you're a purist and have serious goals about performance, then you'll probably end up like me, dreaming about sphericals instead.

Search for "HardRace". I believe they make stiffer rubber [or maybe poly] bushings in the style of OEM. At a guess they'd be priced somewhere between ES and OEM.

A little off topic, but can you guys recommend some places to pick up individual bushes. My hardrace kit only comes with the inner front lca bushing, they dont recommend a solid bushings for the outer bushing when using solid upper arm bushings...

So basically i need the outer FLCA bushings and tie rod boot bushings in poly.

any suggestions as to where i can pick these items up from?

Hardrace do make hard rubber bushings...They also offer the same bushings in a spherical application.

Here is a list of items they stock. I can put you into contact with someone that can supply most of the above if you wish.

As for price...not cheap. for instance, I was quoted $140 US for the front lower control arm bushings alone...in spherical mind you. Rubber is much cheaper. You can buy the whole hard rubber kit off SPM (Special Project Motorsports) for $330 US

i see where you're coming from. but the way i see it alot of bushes in the car would benefit from only rotating on one axis. This is an uneducated view though

i'm running ES at the moment so i'll see how they go. I have definately noticed a performance increase over my OEM bushes (12 year old bushes i might add). Have to keep my eyes on their longevity though.

Same thing goes for all new parts put on the car though. Will have a look at hardrace ones.

Trial and error.

my hardrace ones are holding up pretty well

my mate had noltec bushings installed in his lca, when we switched them out to put in dc2r rear lca's one of the noltec bushings on the lca literally fell apart and all the others were badly worn and basically became ovals
looked like someone had stuck a heated up screw through a wax candle

personally replaced trailing arm bushes with ES ones - did it for ease of install and cost.
No issues , no excess noise. Keeps the rear quite straight - for a semi-daily car they are fine.
But for all other bushes , i recommend OEM parts , be it mugen even. They will last another 10-15 years of use.

Have noltec bushing all round the car. Been over a yr of some hard driving and they still look ok.

I pick up my car tomorrow guys...man I can't wait/can't sleep... every single bushing been changed, fully reconditioned steering rack and brand new tie rods = YUMMY
Will be sure to give feedback for you guys as front end is Energy Suspension, rear end is Mugen

How did you go buddy? Happy with the result?
Contemplating on doing pretty much same as you

Hey EGJOE,

The car has been transformed. It is alive! Where the car felt dangerous and uncertain, it is not confidence-inspiring. I gave it a full and thorough testing along the Great Ocean Road on yesterday's cruise and I couldn't be happier with it. I'll be monitoring the bushes and hopefully they stay in good shape for a long time :-)

[EGJOE]

Thats great to hear the positive result, Good work buddy!!!
Only concern i have is longevity of the es kit. I guess i'll just have to stay tuned.

I think it's very important to ensure that the poly bushes are thoroughly and generously greased up. You can't skimp on this, otherwise the bushes will run dry and start to do all sorts of horrid things.
