why do m's not have adjustable ride height?

IMO H&R does have rebound issues, from the rather limited sessions I've had in some cars.

2nd this. Having experience with H&R (before) and ACS (now), I highly recommend ACS over H&R.

Car sits lower and doesn't bounce around like H&R did.

Does anyone have a pic side by side on level ground of an M5 with H&R springs vs an M5 with ACS springs?

I would like to see the difference. My understanding is the ACS is 10mm lower in the rear?

I always crawl over speed bumps even in my Yukon.

I'd call it mildly detuned. Driven my car (H&R) hard extensively and recent hard driving with stock M5's. Rate is not matched exactly with the shocks - shows on uneven road surfaces.

Is it a big deal in daily driving? Not really...but it is present.

Still waiting on the Eibach's myself.

I'm going to do one of two things:

- Get the competition package springs and try those
- Wait for the K&W DDC kit due out end of this year

Meanwhile, I just enjoy the drop

Oh yeah! Good point! I might get the Competition Package Springs as well if they are out before the Eibachs. Actually I would prefer the Comp Pack Springs to the Eibach's as they are OEM. We'll see though.
