Wishbone Bushes
Hi Guys
It has now been a while since someone produced the polyurethane bushes for the front wishbones, so I reckon there are a few of you out there with them fitted.
Question is , how are you getting on with them?.
Is it a much firmer Ride ?.
Has handling improved ?.
I am about to replace mine and want your advice about which route to take,
I think the PU bushes are still the cheaper option £100 if I recall correctly as opposed to £350 + for new arms from OPC.
Which path should I choose , New PU bushes or new arms.

Dave,
I think the choice very much depends on who is doing the work. If you are paying someone to do it the savings are not as great as you might imagine since the work involved in removing the old bushes (which are designed NOT to be removed) is considerably more than just changing the wishbones.
I went the wishbone route but many have used the Powerflex bushes with great success.
Regards
Dave

I read in 911 world , how to do the job, looks straight forward enough.
Dave computermedic.
Just had a look at your site and all i can say is "WOW" What an amazing site , such a good read.
I have been hanging around here for 3 years and have never seen it.

David,
The ride is not firmer . With no binding in the wishbones there should be no wishbone related ride stiffness.
The handling can be found to be better . The front wishbone front rubber bands can be pretty wobbly . The Polyflex bushes were designed to eliminate that affect .
The flexible front end of the standard wishbone design is rather strange .
I have been running a pair of Polyflex bushed front wishbones from the time
we agreed on the final design , so about four years .
A read of the 911 & Porsche World article will point out how the old rubber stuff is removed and the Polyflex bushes are fitted . The key is to take your time and be careful . If you are in a rush or find mechanical work very difficult , then maybe finding someone to remove the rubber stuff and fit the Poly bushes a good idea .
It is more difficult than fitting a crank sensor !! Sorry , but I couldnt forget that one !!
I have found the way that Porsche have cut the replacement wishbone price
very funny . Perhaps some further replacement part designs would be a further idea !!

From reading the article and what you guys say I am 80/20 in favour of the PU bushes.
Geoff
Nuts and Bolts are more of my thing, and have now found a good mechanic as a back up if i get stuck.
Its funny electrics seem easy when you know how. Its a bit like maths , once you learn the formula , you never forget.
I will maybe order them on Monday, will let you know how i get on.
In the last 2 weeks With help from Jeffnudd, I have sorted about a dozen problems on my car , just one or two more to go then it will be near on perfect.

Dave,
While you are doing the front bushes it would be a good time to take a good look at the shockers . You will need a spring compressor to test the shocks .
For a cabrio i dont think its worth going very far with the suspension . The body shell hasnt got the stiffness . A set of decent shocks will do it .

In terms of the front wishbone ,inner bushes ,the 964/993 are the same dimensions .

Geoff, sorry didn't explain properly!! What I meant was, are the actually wishbones all the same?? I have a set of 6k 993TT wishbone like new as spares. Just wondered if someday in the future the will be suitable for a 964 C2 when the bushes are worn out.
Thanks,
Gary

The springs and shocks are on my wish list but they are quite a way down the list.
At the moment the back looks low while the front looks high, probably due to weak rear springs..
These measurements are taken from the top of the wheel arches , not the right place but for reference.
Friends c2 targa front 663 rear 695
my c4 cab front 670 rear 630
as you can see in comparison mine has a higher front to rear ratio
