Honestly stock springs and the bilstien shocks. I would not want to pair up lowering springs with shocks made for stock springs, ride will really suffer and handling will not be so great.

The HD's are. They used to advertise them as "for use with stock springs only." The SLP Bilstiens are supposedly valved better for lowering springs in the front, and the rear seems to be the same.
Which did you get and where did you buy them from?
Ok... So what springs did you go with?

It's best to research and ask as many questions as possible before buying.
JD AMG is on point. The SLP Bilsteins were used on an SLP Suspension package for SS's which used Eibachs (Pros) made for SLP. You're not seeing much of a differance cause you may have already had the SLP suspension package. With the information you provided, it is unclear what you had and are going to/expecting to change.

In the back of my head I was afraid that you got used shocks. While the previous owner may say they are low mile ones, how do you really know? How would you know they are not blown, or just really worn out? (which I think is the case here). And keep in mind that even if they are low mile shocks, if he had them paired with the prokit, then they have taken much more abuse than they were intended for(because they are valved to work with the stock height, stock rate springs). I've searched and can find nothing on the " bilstein f4-b4g-1913-ho" shocks. FWIW if you go cheap with suspension expect the car to ride and handle cheap, especially the shocks. If you want to see a big improvement buy some quality shocks and springs designed to work with one another. There is a reason the koni/strano combination is so popular.

I'm with JD. It probably isn't the answer you want to hear, but it's relevant info. HD's that were paired up with lowering springs may be worn and unable to perform the way they did when they were new.
What did you switch from and what do you have now? Shocks springs new old...

damn now im pretty upset. well to start i switched from stock decarbons stock springs everything to the yellow bilstiens with prokit. the car seems to ride the same just more stiff and it feels better on turns. and i didnt notice much if any drop in the front. the rear did drop about a inch. and the shock said bilstein f4-b4g-1913-ho on it i havent installed the rears im going to take a pic of them and post it.

Manufacturer Part number for the 93-02 style bilstien HD rear like you have pictured is "F4-BE5-2407-M1", I can't find anything on the part # you have there. Maybe you should call up bilstien and ask them about those shocks.
Either way I would try them on your stock springs because like I already said that's what they are made for, pairing them with lowering springs is only going to wear them out faster, and give you mediocre ride and handling. Kinda like putting in a really big cam in a bone stock engine and no tune, the car is not going to run like its supposed to.

There is no such thing as "SLP Pro-kits". There are SLP springs made to spec by Eibach. There are Pro-kits. There are not both combined. Saying they are Pro-kits is like calling your car a Chevette because it's a Chevrolet.
B46-1914 is the previous iteration of the Bilstein HD *before* they changed the valving all around.
