is it worth replacing all of my bushes with poly ones or do just certain ones need changing to make it handle better?

Personally i would replace them all, however it is a bitch of a job and you will only see a big difference if the ones you replaced are fu*ked(which they will probably will be)

I understand that you're better getting new BMW ones than the Poly bushes, unless you're going to put it on a racetrack.

A lot of people say that.

I have poly bushed everything on mine except the engine mounts and I don't find it harsh at all.

Maybe I'm just tolerant of it after the lowered Minis and Mk2 Escorts etc.! :?

Snap, and i'm using stiff "spax" shocks and springs. May be a different story when the H & R Anti Roll bars go on though :D

Err, this is in the motorsport/trackday forum is it not?

I definitely rate the poly bushes, i've got poly subframe, diff, gearbox and engine mounts on mine and they are great. I did use solid rubber eccentric wishbone bushes after hearing a multitude of horror stories regarding the powerflex version of these.

I doubt it mate, mine still rides like a limousine compared to a Mk2 Escort! :)

I'm using H&R springs though and I reeeeaaalllly rate them highly, sooo much better than the two sets I had on before those!

Next time we meet I'm more than happy to take you round the block in it so you can compare it to yours if you wish?

Polybush all round, BMW M3 on the control arms

Have seen 4 powerflex control arm bush failures, and been told about numerous others, not sure about the other suppliers of polybushes as never seen their CA bushes

I have a full set of poly bushes on the car.

However

A friend of mine who works for Jaguar in the suspension / set up area wrote a large article on this a while back. Basically he feels that new rubber is better than poly. I did post it in this section some time back. It might be worth a read if for no reason than to generate debate :wink:

thanks northloop,i think i may just try replacing with rubber as it hasnt seen new rubber bushes,and then see what the difference is over what is on now

m3 control arm bushes er on the control arms... and what others should i do?
and what does the eccentric thing mean? :mad:

alters the steering geometry..best mod you can do..check the arb link arm bushes...they can be replaced with poly bushes from superflex
