EIBACH spring expert required
Do we have any EIBACH spring experts here. I have an Eibach spring
EIBACH 20/96 343950 RS/F
Does anyone have any idea where this spring originated from. I have searched high and low and cannot find anything apart from Eibach USA denying it is their spring.

Dear Steve,
Thank you very much for the offer of help.
I am afraid they are mounted to my 1989 C4. It lowered my C4 40 mm. It is black and I am going to have to use a boroscope to check the numbers on the rear spring because they have been mounted with the numbers not visible.
They are supposed to be an Eibach equivalent of the Porsche Carrera RS springs but longer to fit the Koni 8741-1216Sports strut and 8241-1104Sports rear shocks.
They are street springs. I hope anyway. I was silly not photographing them when I purchased them in early 2001 from a fellow rennlister. The boxes they were sent it along with the docs were destroyed in a flood in January this year. They were fitted to a RS America and were replaced by the RSR versions of the same springs.
I hope this is enough data. I have run into a problem with our local Swiss auto regulatory (car hating gestapo) authority.

Hi Adrian:
That does help narrow things down a bit,.....
Knowing what shocks they are mounted on and what they are for really helps.
These are not listed in any Eibach catalogs and application guides from '97-'03. I suspect they are a special item made specifically for those struts and shocks.
Sounds like you need the T.U.V. sheets on those things from Eibach in Germany.

Dear Steve,
You hit the problem straight on the head. I think they will show up in application guides from 1990 to 1995 or 96. They were purchased by a RSA owner in the states but I never delved too deeply into this because I was not aware that the Swiss car hating regulatory authorities required separate approval documentation for springs. I had them professionally installed and set up because there is yet another special form for this. This form was duly filled in and certified for presentation. There was not reference on this official form that further documentation was required. The crazy thing is that only the springs need to be specifically approved. You can use any shocks and struts.
I have contacted the Swiss Eibach importer and Eibach Germany and a colleague has contacted Eibach USA. I have no replies yet and the answer from Eibach USA was that these were not their springs.
I am wondering if they are Eibach manufactured springs for another supplier if you know what I mean. This is why I need the expertise of people like yourself.

Hi Adrian:
What was odd was those numbers.
They do not follow any number sequences in all of my Eibach books and these might have been made by an outside vendor or by Eibach for another suspension company.
I've not run across this before as I do not use any Koni shocks. The regular lines of sport springs fit the Bilsteins that we normally use on 964's.
Wish I had something more substantial to offer here.

Dear Steve,
Looking at the part number again it must have been made for a US or UK company. Seeing as I purchased them in the USA it would logically be a US company. The reason is because it uses F for front and R for rear. In Germany they use VA and HA. I wonder if this is an Andial or Porsche Motorsports NA spring manufactured by Eibach.
I have no idea how this could be found out by myself easily,

Hi Adrian:
Those might be an Andial special application. Eibach does some custom things for them.
Porsche Motorsports does not use street stuff, only 60mm and 2.25" race springs.
You might call Pete Sanchez at Andial and ask him.

Dear Steve,
I have sent a message to Andial. It has also been suggested that these may actually be Porsche springs manufactured by Eibach. If the number 964 is added to the part number it becomes 964 343 950 RS/F.
The 96 may also indicate 964 series.
We may be getting closer because if they are actually made for Porsche I can get the paperwork required.

Dear Paul,
You ar enot butting in. I cannot help you just yet. I have ended up back with Eibach Germany and as of yet they have not answered my questions.
I know my springs which I now can confirm are
20/96 343 950 RS/F
17/96 343 950 RS/R
have nothing to do with Eibach USA, RUF, Andial, Techart, Gemballa or Porsche AG. I cannot get any answers out of Porsche Motorsport at the moment.
According to PAG they have never used Eibach to supply springs for factory produced 911s or as aftermarket sold kits from TEquipment of Porsche Exclusive.

Adrian,
The following information may help.
I have a pair of 1991 Turbo S "Cup"springs (rear) with the following markings: #37 90 Eibach Carrea 2HA Cup
I interept this to mean that they are a dual rate spring, rated at 37 N/mm (~215 lb/in) and 90 N/mm (~510 lb/in). the RS may refer to the European RS.
All of the springs I've seen lately are dual rate, increasing in rate when the first set reaches coil bind. Tha last truly progressive rate spring, that I have seen, is the 917, and 935 tapered wire springs. The rate is a continous curve until all of the tapered coils bind, at which time it becomes linear. Much easier to drive.
