Eccentric Bush pictures?

[Adammcf]

CLICKITY CLICK!

Has anyone got a picture of these fitted to their car or a car? Id just like to see how they fit in and alter the geometry etc.

[Adammcf]

Where did Simons post go? Hmmm. Anyway if anyone has any pics or more info it would be cool.

there was a thread on this in January with pics ,I needed it as well as there were no instructions with the powerflex eccentric bushes..I have only driven mine a short distance with them fitted but the steering is much more positive ,,,a good mod...but when you are doing it have a look at the arb link arm as well as the bushes in them were shot and needed replacing as well Ԛ£26 each from the stealers

Adam ... you mean the BMW M3 or Powerflex ?
Got Powerflex pics if that helps but they push the front wheel forward by about 1 inch.

Adam, what post do you mean?

[Adammcf]

It was from Simon13. Cheers for the picture though. I take it those are the standard M3 bushes? I am very tempted in getting the Poly ones for mine.

[Simon]

Yeah, they're the standard M3, though poly ones work in the same way though.

I would recommend you get the Solid BMW Late M3 ones as in the picture put up by simon.

The solid ones will perish eventually whereas the Powerflex wont.

Sal we both know that the BMW ones are much better, despite that fact they 'might' perish after say about ten years on the car. (there is no proof of this)

Yet again you think you know it all.

Why are the BMW ones better??

Your first BS theory was thrown out of the window when you suggested the BMW ones were more offset - I showed you clearly by lining them up this is not the case.

Your second theory that the castor is adjusted as the suspension travels downwards is also very flawed. Why?

Because the suspension has to move very far for this to happen and in reality this is not going to happen. Even if it did the BMW bush would stretch to give the same effect.

Please think about what you say before you start confusing people and make them spend their hard earned money on something which will perish.

You want proof of M3 bushes persishing? Why do BMW sell so many of them for a start? They tear quite badly on track days.

Look mate the guy wanted some advice (well pics of off set bushes) he said he might fit the polly ones on, i said that hes better off with the BMW ones as i have experienced both and i still stand by what i said to you.

First off there was about 3mm difference between the two bushes when aligned (and when you think about that the ratio between the offset and caster increase, the BMW increased the castor by 15% on the solid offset bushes the Polly ones might be around the 13% mark)

The polly ones can be fitted by hand (except the black one which needs to be pressed in, but you can do this with a jack) there is far too much slack in this type of setup. With the BMW ones you need in excess of 10 tones of hydraulic press to fit them (this is much better as there is less slack with in turn means less geometric change in the suspension when its under load)

Thirdly like you said the polly design has limitations in that when the control arm moves up and down the caster angle changes (and so does the toe) this is enough to unsettle the car at speeds and on track. I had both bushes side by side and even the slightest rotation of the purple section resulted in noticeable changes in the orientation of the centre point where the control arm entres. Anyone who has fitted the polly bushes will know what i mean.

Ill try and sort out a little VID to show you how much it really is.

If you also knew the limitations of the mac pherson strut design you will also fit the BMW solid bushes.

Im really sorry if this type information will affect your trade on the shop but for an extra Ԛ£30 i would advice people to stretch to the M3 ones. (maybe you could also sell the BMW ones?)

what differance to the car or the way it drives does the m3 bush do ?
Obviously looking at the pics there it moves the wheel in the arch forward a bit but what does this do to the way it drives ?

cheers

Ok folks I didnt want to cause any arguements!
Looks like its going to be a harder decision than I thought!

[Simon13]

i think the main point in them is for a crisper turn in?

Dinan in the states used poly bushes, but cars in the hotter areas over there started to squeek badly when they dried out, and in some cases crack.

This will happen here aswell after sometime too.

So Dinan's solution was to go to bmw's rubber bush makers and get them to make them in a harder compound! job done

Adam poly's are too hard u just don't want them on a road car imo

Demlot - you live on some ANAL planet mate. I dont like saying things like this but I have alot more experience than you when it comes to actually driving cars with different parts.

Poly vs BMW Eccentric bushes is NOT felt on the road! You can stand by what you say for the rest of time - you still dont know what your talking about.

I showed you both bushes line up exactly and you agreed. Now you suddenly change your mind. Looks like to me its not the bushes your worried about but you dont want people buying from me - (see you BS H&R comments as another example).

The poly bushes make no difference at all to harshness unless you fit the subframe ones and even then its hardly noticeable. You can ask all of the people who hve fitted them.

The bushes are supplied with a lubricant (this is for the bushes Andrew and not you!!) so they dont make any noise.

Kermit - we all know you only listen to what demlot says so your just going to repeat what he says - dont bother because we already know what you think

come on lads lol !! ive put accentric front bushes on my tech 1 and a brand new steering rack the difference is very good however ive got other bushes needing doing so cant feel the full effect now lord lend me a money tree lol
