All,
I'm trying to get the warranty company to replace my rear suspension components on my '95 (referring to my previous post):
1- 993.331.041.02 A-arm L
1- 993.331.042.02 A-arm R
2- 993.331.045.03 Kinematic link L&R
2- 993.331.047.03 Camber link L&R
The porsche dealerships are not saying yes or saying no when my local wrench asks them if its possible to replace the updated ('96-'98) arms w/o replacing the links along w/ them but are willing to sell them independantly. Basically, if I am understanding correctly, they aren't saying whether or not the arms are actually different from '95 to '96. Anyone have any hard evidence of this? According the PCA tech site, the actual answer is a definitive maybe. Thanks

Here is the TSB link - this should help identify the updated parts

That well intended link identifies series chassis changes to springs, shocks, and bars: it is silent on rear suspension links and A-arms .... perhaps there is another TSB?

Yeah, that info refers to sway bars and such...Ted, if you or anyone knows of any other bulletins mentioning the links and arms, that would be extremely helpful. Thanks again all

It's interesting to note the level of detail considered in Porsche's TSBs. If there were any geometry changes in the 1996 rear suspension parts, you couldn't just drop in arms randomly to a 1995 car, so Porsche would have definitely put out a TSB on that topic. If they DID NOT put out a TSB, that would speak volumes as to this question.

There is no TSB on the rear chassis apart from the one posted above concerning the 94/95 model.
What is noted though is that the control arms-wheel hub-etc, have a certain part number for 94, another for 95, and another for 96-.
But when we look at an earlier control arm details for stock or price, we are advised that the part number has been replaced with that of the latest part number (for 1996-).

After looking at this TSB it appears my very late May 95' build 993 has no issues with this and has never had a wobble problem even before I did the suspension.

This has been a topic that has been beat to death on this forum and PCA tech site. I believe I am struggling w/ it right now. Basically, the car drives like a fire truck w/ rear steer.
If you're interested in reading more, go to 4/23 date on this site and look for my thread titled 'Lowering 993 w/ 18s (and the '95 "tail wag")'.
Or, just go to the PCA Tech Q&A site for 993 suspensions and type in "geometry". You'll find out a ton there.
