993 replacement Polyurethane Bushes 993 ? help

[sundeep]

on my 993 targa..(still on 17" rubber) about to replace the shocks (bilsten B6) springs (m030) uprated the anti-roll bars (993 turbo spec) but te question of what to do with he suspension wishbone bushes...

using a specialist (AmD) who confirm that I would need to replace the both lower arms with bushes...

but as I read in last years 911P&W replacement Polyurethane Bushes are available which are much more cost effective £100 a set(?) then the entire arms at £200 each !

The issue is ride quality and will it be too firm to live with, in view that this is my daily car and track day car ! AmD say it will be too firm, but on the not so hard Bilsteins and 17" rubber will I cope ?

anyone else tried Polyurethane Bushes ? words of advise please !

If it's any help, my 993 Targa needed new bushes last year. I drew my Porsche independent garage's attention to that article and was firmly advised not to go down that path. The mechanic I've known a long while told me that it was easily possible to damage the suspension arm in the process of driving out the old bushes and it just wasn't worth the effort. According to him, if done by a garage, the labour costs would equate to the cost of buying a new Porsche original replacement suspension arm. I had new arms fitted - peace of mind.

You pays your money and takes your choice.

The mag had to print an apology the following month because they had not checked their facts re prices.

I raised the very same question and was told that the ride would be seriously compromised for a daily driver, worse I would think for a Targa.

Just had mine replaced with the polyurethane bushes. Haven't driven it much yet but definetly feels much better combined with the Bilstein HDs I also had fitted. My garage said that they had fitted several of these poly bushes and have had no negative feeback.

The only negative feedback I had was on the standard OEM bushes whiche were described as crap. They have cavities which give a more cushioned feel to the steering. This is one of the main reasons the steering on 993's feels a bit woolly.

Fittd polly bushes to my Cup Car after the OE ones only lasted 2 1/2 years, 10,000kms.

Absolutley no discernable difference until the fule load got below half a tank where understeer came in earlier than usual.

The bushes ar readily available at about £100 + VAT per set. Then labour on top to remove and drive out. Any careful specilaist should be able to do this without damaging the wishbone arms.

I have a pair of wishbones suitable for rebushing if anybody wants to use them in exchange for a rebushed pair and not have to take their car off the road for too long.

I've got these on my 964 - don't feel too firm (and I have Bilstein HD/H+R suspension). I like them. Overall cost was about the same as just replacing the wishbones. The work was done by GT1.

Powerflex I believe, maybe from Milford.....



I also beleive that 911&PW did a write up on how to replace the 964 variety, I d/l'd a copy from some website somewhere that now eludes me..

cheers for the replies...

the article was in the June 04 issue of 911P&W.. checking the july 04 one as you mention !

£100 for bushes v £400 for a pair new wishbones

but surely the labour on the bushes can't be that much.... would like to save that £300 ! but on my 90k mile car the bushes must be past it..(?)

a trickly one... I know it will help on track but the issue is on road ??? esp in the targa !

[sundeep]

for those who have had 'em fitted which garage did you all use ?

[randeria]

I had the Powerflex bushes fitted on my 993RS in February and they are absolutely fine. Done three trackdays since and the car handles beautifully. They were fitted by GT One in Chertsey.

You should be able to get the bushes from any PowerFlex stockist

Try giving.

A call
They are supplyers of Powerflex bits....

GT One - it was an hour or so extra labour to remove and replace the bushes in the wishbones (but mine were the first ones they had done, last November). Also bear in mind you'll need a full alignment, whichever way you go.
