Larry,
As my car was referenced in this thread, I thought that I would add a bit of information to the discussion. From my experience, the early 993's did/do have rear geometry issues, that could lead to "diabolical" handling, once they have been lowered/stiffened past a certain point. As my car was raced in the Cup series prior to it landing in the USA, the spring rates were very high (1100 & 1350 come to mind, but I would have to check), and the car was very low (the spring/shock rates and ride height were comparable to other 993 Cup cars). Given this set up, the variable length arms in the rear made a world of difference (I know of at least one other friend, with a similar car, that would agree)!!
Unless you are moving toward this type of a set up, I believe that the stock arms should work very well. As mentioned earlier, I would also recommend Joel as an expert in this area.
One final note, if you are changing springs, make certain that you use an appropriately valved shock (I have had the mismatch issue on 3 cars, and have seen several threads on this topic). If the spring/shock package isn't a good fit, your handling can deteriorate significantly.
See you on the track....
