Updating the rear suspension to 1996 specs is an utter waste of money, again, iMHO. A few guys on the board have experienced the alleged and dreaded 1995 tail wag, a problem that was remedied by installing ERP bearings in the rear. I have never had crazy or dangerous yaw issues with my 1995 car. I completely respect Joel Reiser's experience and skill, but there are just too many 1995 993's that are being raced or tracked that have not had problems regarding a rear end stability as it pertains to suspension geometry. Sloppy rubber bushings, yes; geometry, no.
Mark, after much research and looking at the cost of replacing the rear parts w/ 96+ parts or RS parts I replaced the rear bushings w/ Weltmeister/ERP bushings and had the car aligned and haven't looked back.

Thanks. 
Pat, you were the person I had thought of who had experienced issues that were ameliorated by replacing the bushings with bearings. I thought they were ERP's

I'm going to be doing DE's with my 993 (haven't gotten it on the track yet), and here's my basic budget:
$1K Shabby 17" cup wheels & track tires
$750 DAS roll bar (found a perfect used one)
??? Seats and sliders (looking for good used PP's, not likely. Already have harnesses)
My car came from the PO with PSS9's. All told, I'll probably be able to put it on the track and have fun with it for about $3K in mods. I've already put on the RS heater tube, cat bypasses, manual oil cooler fan switch, and pulled some weight off of it. I'm sure it won't be long before TRG sways will go on the car as well.
If you're DE'ing a 993, there really aren't that many mods that you *have* to do to make the car fun and safe on the track. I lucked out in finding a car that already had a decent suspension on it.

Thanks for all the input guys!
My main motivation to build a track 993 is to have fun, yet safe 911 to toss around on the track.
I'm currently tracking my GT3 and god forbid I mash it to the wall, I'm out of $70k.
Therefore I'm looking into getting something a bit cheaper so I can have a little equity sitting in my bank account just in case I happen to wreck the car on the track.
BMW's, boxters, 944's, Miatas etc. just won't cut it because I want an 911.
An early 996 would probably give the most bang for the buck but after owning and tracking the the GT3, they just won't appeal to me.
Sooner or later I would be building a wannabe GT3 anyway and at that point I would've been better of keeping the GT.
Like many people said, there are a lot of good deals out there (already prepped 993's). I'm not looking to going racing anytime soon either so that will give me a lot more flexibility when choosing the car and mods.
I just wanted to get a general idea on how much each item that the car needs will cost.

Maybe I haven't been looking hard enough but I have not seen many 993 track prepped.

JUha,
I haven't read all of the posts, but based on your costs on page 1, you will need well over $2k for a suspension setup that is even reasonable for the track. I would say a minimum is PSS9s w/ RS or other adjustable sway bars. Additionally, you need to add in 1.5-2.5k for auxiliary oil cooling which will be needed.
I'm going to be starting this effort shortly. My situation is that I already own almost everything since I pulled it off my C4S and just need to put it on the C2 donor car, so good luck.
