The difference between all these setups was downright obvious on my car. The Konis were soft based on bumper push and soft based on driving. Cadillac ride. With the rebound damping cranked up they were sloppy on compression and harsh. The Boge Reds were about as soft on the bumper push as the Konis, but better damped on the road. The Bilsteins/Eibachs were strangely annoying (jiggly, nervous) with poor bump control, perhaps due to some mistake in assembly (the springs are shorter and the rears did not require a spring compressor - weird). The Bilsteins with my stock springs (I do not have sport springs after all) seems to be just about perfect - WAY firm on the bumper push, but civilized and controlled on the road. I think for everything but the track, where you might want everything dialed up even firmer, the Bilsteins or Boge Reds will work well. Good for daily driving, good for twisties and good for high speed stability and control for open road racing - that's what I need. I have no experience with Hypercoils, but I know they have a good reputation, as do the Eibachs. At this point I can't explain my adverse experience with the Eibachs, although a few others have had similar experience. Making sure the ride height is up, which preloads the springs, seemed to be important. My handling improved, and, of course, I had fewer front spoiler hits in turns, as I got the ride height close to stock. But even at 160 front and rear (still below stock, but higher than most people run), these springs had strange street manners. No such anomalies with the same Bilsteins paired with stock springs.

There really isn't any clear indication they are bad, but when my car was wallowing around after a second set of shocks, I bought them thinking that had to be it. I want to change out the steering rack first. If that and an alignment fixes the sensation of wandering and tramlining, then I'll just save the bushings for later, as I don't think they are contributing anymore. The wandering and tramlining seems better after the final shock change. I might have changed the front alignment for the better with the lower A-arm removal and reinstallation required when changing the front shocks this last time.

The digressive valving of the Bilstein gives you firm resistance to slow movements like when you bounce the car BUT softer resistance to quick movements which is just part of what makes it a far superior design than that of other older technology shocks. I am just very happy to hear that you got it sorted out to your satisfaction.
