Nik at Willow sports cars poly bushed the whole rear end of my car including diff bushes .He was not very impressed with the bushes I supplied from Steve Heath . He shown me the poly bushes he uses and sells ,they were completely different ,Niks bushes seemed to have a lot more meat on them so less harsh .

Peter is the man to ask 
he is a good bench for stuff like this i.e track etc and the one's he was using he raved about how many trouble free miles he had covered

Its a personal choice thing, but I'd only ever consider going poly bushing on the front & rear ARB mounts, and perhaps the diff mounts too.
But that's it for poly bushing, all wishbone bushes should be OEM metalastic as far as I'm concerned.
Take a look at an OEM bush and you'll see there really isn't a great deal of rubber in them, which means they're plenty stiff enough.
But nothing isolates noise, harshness & vibration like rubber, which is why Ferrari, Lamborghini, Aston Martin, Porsche ect ect still exclusively use good old fashioned (but highly effective) rubber bushing.
If poly really was the holy grail of bushing materials these manufacturers would be using it.
Willow does offer some natty little wishbone bush heat shields though, irrespective of weather you choose poly or rubber wishbone bushes I'd say the heat shields are a no-brainer on any Chim or Griff.
But these heat shields would be especially desirable on a turbo car like Rich's where exhaust temps will be even greater than the standard cars.
All this is just my personal opinion you understand

I just had a mare getting the old OEM lower rear wishbone to upright bushes out the bolts seized into the the bush and access was rubbish to saw the bolts off, if the poly ones are two piece and stainless sleeve that should never happen, but I don't want to be replacing them again in a couple of years

Thats what i thought with the polybushes , easy to change but shouldnt wear out that quick!! Nah stick with what works ..... Standard. Hoofa said:

Not had them on long enough to comment on durability but for (relative) ease of fitting, apparent material quality, and driving 'feel', I'm happy with the Powerflex Black bushes I fitted to the rear throughout. There is a definite handling improvement over the OEM metallastics but so there should be given the mileage they had done - I was quite surprised that all bar a couple were still firmly bonded however; was fully expecting a mix of black and brown crumbly dandruff to be holding the suspension together but they were still largely intact so certainly wouldn't discount replacing with the same if you can tool up for the faff of pressing the buggers in..

Just came across this thread by chance, normally residing on the classics section (M's)
It is recommended by various people for the M's to put metalastics (OE), on the 'weight-bearing' bushes (inner of the wishbones), whilst the outers get poly'
Perhaps it will work for you guys as well ?

I fitted Supaflex to my 4.6 about 4-5 years ago and have covered about 35K since then.
It was MOTd at my sons garage recently where I asked "the man" to give it a thorough going over suspension wise and all was sound.
So for me it was "fit and forget" .
Easy to fit,.... did it feel better, can't remember what rubber was like, (oh, apart from last night ).

For most car set ups and drivers, I'd say the above is spot on. It's definitely a question of YMMV, though. But that's it for poly bushing, all wishbone bushes should be OEM metalastic as far as I'm concerned.
