Polyurethane Bushes ?

[Fudgenudger]

I have ordered some polyurethane bushes for the rear diff mounts and front and rear antirollbars mounts, due to, especially the diff bushes being totally split.
I was thinking of going the whole hog and buying the complete set for the front and rear suspension.
Im sure this question has been asked many times before, but can you guys advise this to be a good idea or not. I have fitted polybushes to previous cars including a Golf Mk2 GTI and a classic shape Impreza Sti and have found that they work fantastic, so I don't mind the stiffness of the bushes, but wonder if they work well on Cerbs ?
Also are Powerflex the best ones to use ?
Cheers.

I fitted a set to my last TVR Chim and cant say i noticed any change to the way it drove so i wont be doing it to the cerb unless they need changing.

I have all mine Powerflexed for the last two years or so.

It transformed the car and I'd say to go for it.

I asked that a while ago http://www.pistonheads.com/gassing/topic.asp?t=911000

Still not 100% but think I'll stick with just getting new rubber ones. Would be good to hear from some one who has fitted poly ones who thinks they haven't made the ride any harder though....

Powerflex polybushes throughout certainly didn't make my ride noticeably harder. They made very little difference to the feel - possibly slightly 'tighter' handling but certainly not harsher. That is until both front drag strut bushes disintegrated after a few months when it started to feel very strange! I replaced those with standard bushes an have had no further problem. The rest of the polybushes have been fine.

ETA. They made disapointingly little difference - when the time comes I will almost certainly be replacing them with rubber.

I have just fitted them all round to my Cerb, including new drop links, adjustable shocks, and rear Tuscan wishbones, have also fitted the revised steering rack spacers, and Rose joints. Dan at Taylor Tvr has set it all up but I have been on holiday for the past two weeks and so have not given the car a proper run as yet. I will keep you posted. I used power flex bushes.

Yea, think I will go for it and fit them over the winter, one or two people advised me against it but they do not even own Cerbies, in fact one of them owned a Land Rover Disco and fitted the bushes to it He said he took them off after a couple of weeks, but why fit them in the first place !
So maybe I should definately take advise from him

I think that the main difference you notice when replacing with poly bushes is because they are new bushes. not because they are poly ones.

There is also an argument the I have heard that says the metal sleeved rubber is better in a rotating bush than the unsleeved polyurethane. I don't know if its true or not, however my drag strut poly bushes only lasted a few months before disintegrating.

If your bushes are knackered and need changing anyway -then why not - but if they don't need to be changed put the money towards a set of Nitron shocks. Now they will make a big difference!!

As some of the bushes definately are quite bad I thought I might aswell replace all of them. Im sure I got quoted with the ones with the metal sleeved rubber. I already have Gaz Golds fitted, they seem to be fairly good but do not know how they compare to Nitrons?

[Tanguero]

I haven't tried Gaz Golds but I had a set of Gaz Nickel fitted just after I got my Cerb. They were a bit of an improvement on the original shocks. They lasted around 3 years before they started to leak and squeak at the front. I changed them for Nitrons all round for sprinting and they are a whole different ball game!! Completely transformed the handling. Tighter, grippier and more predictable all round.
