H&R / Eibach spring comparision with pics

Hi all.
I picked up a touring about a year ago, and it had H&R springs on it with stock struts/shocks. I bought it sight unseen from Florida and shipped it to Colorado and so far it's worked out great.

I decided to replace the shocks/struts, and since it all had to come apart anyway I wanted to try the Eibachs. I'm old and brittle, and the promise of a slightly cushier ride plus incrementally higher ride height were primary considerations. The shocks/struts are Bilstein B8s.

The comparison is somewhat compromised because the H&Rs had worn out stock dampers. The rears were gone, with effectively no rebound; I compressed them when they were off the car and they expanded in hours, not seconds. There is 140K on the clock, so who knows how long they were on the car. Car has stock swaybars and most bushings have been replaced.

Ride: The Eibachs have more initial compliance than the HRs. They seem to firm up nicely under load, but not as much as the HRs. Because of that the HRs seemed harsher, but that harshness could be attributed to the stock dampers that were worn and couldn't keep up. The Eibachs don't float on undulating surfaces like a stock Xi might, but they do more to smooth them out v.s. following the surface like the HRs did.

Height: The pics seem misleading, and it doesn't help that I was unscientific and didn't ensure that the ruler placement was identical for each measurement. The car sat visibly lower and more level on the HRs than with the Eibachs, to my eyes.

Handling: The HRs win. Lean was effectively absent, and the car seemed snappier and more responsive to steering input. The brakes seemed more effective with less weight transfer. The Eibachs are a little slower, with more weight transfer (but not a lot, only in comparison)
My handling summary is that the Eibachs are an excellent daily/good occasional track type of setup, and the HRs are a good daily/excellent often track type thing.

The pics follow.

More pics. springs side by side.

Decided to do the Rogue rear mounts too, since I don't want to tear into the interior again. I consider them worth the cost.

thanks for this. right now i am running b8 shocks with just regular struts and regular springs (bilstein b3).

first i am going to try just the lowering spring seats (supersport suft015). but at some point i do want to try these lowering springs.
