Rear sport Spring loose on Bilstein HD shock!

I fully uncompressed the rear spring (stock sport) on Bilstein HD shock (part # 24-028288) but it's not tight. I'm still able to move the spring at the top and bottom pad. I expected the pads to be unmovable when the spring is fully uncompressed and the compressor removed, just like the stock shocks I removed. All the components (cap, mount, washer etc) are properly installed and there's nothing obstructing the spring from fully uncompressing. The spring is certainly full uncompressed and properly sitting and correctly oriented on the top and bottom pads. It's as if the shock is a bit long for the spring.

This fitment does not look normal to me, or what am I missing? I'm not confident installing it like this.

Your post is a bit confusing but are you sure you have the correct shocks installed. Everytime I've replaced shocks on a car with sports suspension (& hence sport springs), I've had to use sport shocks (Bilsteins). It would appear that your shocks are too long for the sport springs.

Did you mean the shock is too long for the print? That would account for the spring being loose. Post up pictures of how the springs are sitting in the spring perch. That will tell us if they are mounted correctly. Did you refer to the Beisan procedure for installation?

Yes, meant the shock is too long for the spring - I corrected the post. Here're the pics. Although the spring is sitting properly on the pads, I can still rotate the pads. May be I should tighten the top bolt more? It's torqued to 16ft-pound. I see that C90 has the same shocks in his car with sports suspension as shown in his DIY for rear shocks which I was using http://www.bimmerfest.com/forums/sho...d.php?t=545345. I bought the shocks (Bilstein HD 24-028288) at TireRack and they're applicable to both standard and sports suspension.

The Bilstein shock HD is longer than stock sports. The longer shaft length of the HD is leaving the sport spring loose between the hat and perch. Should I just go ahead and install them like this and they'll be ok when the suspension is not at full hang? My search shows that folks have installed these shocks with OEM sports shocks. Any one in here installed them?

My findings for future reference- this is normal before the shock assembly is installed into the vehicle:

But, I will exchange them with koni sports after reading the above thread. Very informative.
