OK, after 3 tries I've got it right. I originally ordered a set of Eibach Pro-Kit springs (1 inch drop), and a full set of Bilstein shocks. I didn't know the front Bilsteins had to be revalved (the rears are fine). Upon installation, the front of the car pogo-sticked badly, so I ordered another set of front Bilsteins, and on the advice of Jack French there, had them revalved to 100 compression, 300 rebound (the original specs for them are 46/195). This +almost+ solved the bouncing, but not quite. After the original deflection, the car wouldn't come back as quickly as I liked, but it was very close. So I sent off the original pair and had them revalved to 110/340 (about a 10% increase over try #2)). Just got them on today, and this IS the setup for Eibach/Bilsteins. Any firmer on the shocks, and the ride would be too harsh with no gain.
To me, the extra 10% was worth spending the $65 per shock revalve charge + about $28 shipping + $100 to install. But others could probably live with the 100/300 shocks. I now have them as surplus. they're practically new, as they were on my car about 2 months. Anyone interested let me know.
ps: This has been a real educational experience for me. I had no idea about how important it was for the springs and the shocks to be matched correctly. I have had cars that others had modified in this way, and in retrospect, I think that most of my shocks were too firm, unnecessarily so. What you want is the initial deflection to come back and stop evenly, no more, no less. The problem is, without adjustable shocks, the process of getting to the optimal setup is expensive and time-consuming. I personally think the site here should come up with a list of shock/spring combos that have been tried and shown to be perfectly matched. That way the next guy down the line won't have to reinvent the wheel.
