Has to do with weight distribution (think of it as corner balancing). You can put your weight in steel weights on the driver's seat, too.
I don't think it matters all that much for a 160 lb guy in a heavier car like a 993. On a light sub-2,100 lb autocross Miata - I insist on it.

OP I had the same problem with my Cab when I bought it. It was one of two things.
The rear KT alignment, toe in toe out caster alignment that Porsche only shops know how to do. https://www.paragon-products.com/v/v...toe%20reva.pdf
The front control arm bushings. I was told mine was fine but they were original and I changed them, http://fdmotorsports.net/suspension-993/
If you have a 95-96 Cab there is a TSB to install a support on the steering rack if you use any size larger wheels. http://www.pcarworkshop.com/images/5...996_640496.pdf
I did all 3 and solved my problem. My guess is the rear alignment caused the most dramatic effect.

I can't figure out whether to start buying the suspension parts, collecting them over the winter and then bringing them all into a garage in the spring or waiting to find a garage and then have them order the parts while they're doing the work.

I wonder why you can ID the rear shocks as being new Bilsteins but can't ID the front? If you have old shocks in the front, or they are mismatched, that needs to be corrected BEFORE you waste time and money on alignment.

Fantastic, thank you for the info. I have a '98 so I'll stick w/ the first two suggestions. I suppose there's no point in getting an alignment until the suspension has been replaced.

As long as you have the parts numbers this place/dealer has OEM parts at around 40-50% off retail. But you have to know what your ordering. http://store.paramountauto.com/auto-parts/porsche/911 you put the part number on the top line.
Suncoast Porch is probably the best place to call and order the euro springs.
Aftermarket parts I would get from Pelican

I put the softer (lower ride height, but standard stiffness, not sport) M033 euro springs on my C4 coupe and like them a lot.
I bought springs and Koni FSD shocks from Carnewal, but they also offer Bilsteins.
