Poly-bush v Genuine Part

[danny_p]

spherical bearings.

you use them when you do away with bushes completly, they mean your suspention gemetry will stay bang on even under silly loads, as there is no rubber or polyurethane to distort. 


they are for balls out motorsport on smooth surfaces.  youd feel it if you ran over singel stray bit of gravel

as the name says they are literly bearing  but they allow angular movement

They look wicked!

Bet that'd smash your spine on a daily

You need to clear your workshop up

not my workshop i nicked the  photos nicked of vwvortex       but you are right i do need to tidy the ws up again 

my workshop camera dint like takeing photos of welding still not bought another.

they would, they don't last that long ether, the siffer you make things the higher the shock loads become. with sperical bearings  metal fatuigue becomes a real problem things have a nasty habbit of cracking and snaping  so regular inspections are needed   the reason i'm not going down that route as i know   id take the car out on the road for a play every now and again and i dought id check the suspention arms often enough

The main benefit of polybushes is that they last considerably longer than OEM bushes, however they're used.

How'd you figure that one then?  Did you read a polybush advert? 

If you can find uprated OEM (like the TT bushes that fit the G2 lower control arms) then I'd do that.  In my experience OEM bushes last a lot longer than polybush replacements.

oem lasting longer than polybush? obviously this is s a wind up.

On what basis is it a wind up?

sorry, I thought you were kidding about oems outlasting polys. I had lower arms and rear axel polys on my mk3 for years.

So did I N loved them. So much more positive than the rubber but then I had good setup and not cheap crashy coilies. They provided a fair bit more feedback but DH is right about the amount of wear on other components as a result. Still worth it IMO tho.

You're mis-reading my point - polybushes don't last as long as the OEM equivilent.  The load transfer problems they bring are another (horrible) subject all together.

If you want any more evidence of this, have a look on Nige Pinder's build thread on Northloop.  He was junking polybushes on an annual basis.

I ran them for 4 years and 40000 miles with no issues on a car dropped 40mm with koni adjustables wound pretty hard. I was never shy in the corners either

Suppose some of it depends on the qualityofthe bush inthe first place
