E39 suspension setup

Been doing some research on lowering my car. I know everyone says to go with bilstein, but if I wanted to go with Sachs sports. What is the best spring for this set up? My car is my daily drive. Thanks for any info, Remember I know bilstein and koni are the best, but I am trying to keep it stock. I am looking for opinion from people running Sachs sports springs.

You may want to consider using the sport suspension setup (springs & struts) from later models (01-03) although I cannot confirm that they would fit (I believe they are compatible). I find they give an excellent blend of ride quality and handling. And they would lower your car just a bit without risking bottoming out.

Why not just get the stock sport spring for your car? I put Koni Sports to replace my stock struts (M5 for 03 540), ride is very close to OEM. Kept same springs.

For springs, very close to OEM, you could get the Vogtland 951027 JDM Werks has them (e-bay linky) for 219.62$.
OEM sport springs are more expensive I believe (if new).

Is there really a difference between those two?

One will lower the car more than the other. Typically a shorter spring will also be stiffer than a longer spring to reduce the likelihood for bottoming out due to the shorter travel length.
