Hi, i have had a look through the search but this topic seems to vary hugely.
I want to replace all bushes for my build, the only ones i dont need are arb's and diff mount as i have these.
Its a track car, but will also be used on the road, but not as a daily driver.
Should i fit oem or polybush, or perhaps a mix? I also understand i can fit eccentric where possible.
I have heard that the poly's can sometimes cause issues and come loose, not last long and also make the ride awful.
Can you recommend any suppliers for either option?
Cheers
Christian
polybush or oem

I use polybushes on my cars,in all locations except the rear beam mount.
I am prepared to cope with the transmitted road noise as I get a tighter feel to my cars.
Rear beam is designed to allow a bit of rear wheel steer,fitting polybushes removes this 'safety net',so I would not recommend for this reason.

Same as what daimlerman has said... Perhaps go for lemforder (oem) on the rear beam and poly the rest seeing as it sounds like its more for track use..

The 75a poly bushes should be a good compliment to modern tyres (which are capable of generating more force than 80s tyres) and behave a lot like the void fillers but a full 90a bush is too hard agreed.daimlerman wrote:I use polybushes on my cars,in all locations except the rear beam mount.

Cheers guys.
Would it be well worth considering buying new front control arms with ball joints? Is there a recommended place to get these items?

If buying complete arms,look for Lemforder items,contact meatballs82 for a price,he is the zone contact at ECP.Stonkin wrote:Cheers guys.

Another option is just to swap the balljoints in your existing arms,but for this you will need the proper tool,available from ebay for about £100.If you ask BSS325i nicely,he can probably put up the link again.
An advantage of using polybushes on the wishbones is that they are in two parts,so can be swapped onto replacement wishbones at a later date.

No BMW special tools required to change ball joints. A hydraulic press and associated accessories is desirable, but it can be done with an angle grinder, a large punch, an even larger hammer and a block of wood or two.daimlerman wrote:

The special tool is for removing control arm bushes intact (which you won't need to do if you change the ball joints), and even this can be done by hand if you lift the rubber around the pin with a small screwdriver and introduce a little silicon grease at several points around its circumference.

I'm sure i read that if you plan on fitting eccentric powerflex polybushes they will only fit onto lemforder arms? Anyone know if this is true

Why not just use the BMW eccentric bush? Solid rubber and wont fall out, £30 odd for the pair.

No, the tool Malcolm mention is for removing an replacing the Ball joint without messing about with removing the arm from the car and using a press, not for removing the control bushes intact although there is a tool for that as well.Brianmoooore wrote:No BMW special tools required to change ball joints.

Thanks,Barry.
The first time you mentioned this tool,I had just replaced a pair of wishbones,buying the tool and the balljoints works out only slightly more expensive and leaves the tool 'paid for' next time....
