What is the freakin difference??
93-02 Bilstein HD Shock Package (Set of 4) $349.99
Improve handling with these precision Bilstein Mono-tube high pressure shocks. The single tube designed shock is filled with oil and nitrogen gas in a pressured, sealed compartment. A dividing piston exerts constant pressure on the oil, which eliminates any oil foaming.
__________________________________________________
93-02 SLP Bilstein Shock Package $382.95
These shocks are built to SLP's specifications by Bilstein and are for use in road racing applications. They give excellent control for daily driving and provide a competitive edge on the road course. The shocks are valved to produce a comfortable, yet firm ride on the street. But they also perform like a race shock during road course maneuvers. The ultimate in a non adjustable dual-purpose shock.

SLPs are revalved to SLP's specs. I don't know what they are, but my understanding is that the SLPs are valved to give a balance of handling and ride comfort with stock springs. HD's probably won't be much different.
Since you're lowered, you'll probably be just about as good with HDs over SLPs. Of course, there's also going to be some who'll recommend Strano revalves (which are valves specifically for your car).
Again, just my guess - I'm certain others will be able to give more specific differences.

I sell HD's for $349. But I use an older rear valving that nobody else does because last year Bilstein screwed up a "new and improved" version. The Hd's one gets from me are not the same as what everyone else has. SLP's version (and I also carry those) are tweaked for SLP springs. They add more rebound in the front shocks, which is good for performance... but they also take compression damping out, which isn't so hot. And in the rear there is no difference.
Basically, I'm not crazy about the cataloged HD's, or the SLP shocks. BTW, those pics and descriptions are pure sale pitches (and while the pics of the SLP shocks are indeed F-body shocks, the pics of "hd's" are not--they are actually truck shocks.

I have always wondered this myself seeing I have the SLP Bilstein suspension on my car from the factory.
So, Sam, are your HD's a good choice for those of us who have the stock SLP Bilstein suspension with the SLP variable springs?

No. Either stay with what you have, being they are at least valved to be a ok match, where HD's weren't. Or, when the SLP shocks become overly soft, move up to Koni's.

Not to get off subject but does the SLP Bilstein and Spring package drop the car any? I am considering this setup because I heard it is a minimal drop (1" or less) and a better option to my decarbon shocks and stock springs which need replacing.

take a look at my pics and judge for yourself. I have the SLP issued Bilstein suspension. It's definitely lower than the non-equipped cars, but don't know how much.

Cost is similar (Koni's start @ $740 vs. I think about $677 for the SLP stuff), you get around a 5/8-3/4" drop in front, about 1/2 in the rear, and shocks with a lot more flexibility. Why do I like this better? Pretty much because the dampers are much more important to a good working car than is a spring change. Not that springs don't help improve the car, but the dampers are the key in my opinion.

I had my SLP levelII for about 2 years now and it's OK but the front is a bit too spungy to my taste. The shocks/struts are for levelII but I believe they are the same valvings as the regular SLP shocks/struts.
If I had to do it again, I would go with some koni's for the front.
The car lowered a bit in front and rear but not by much.

Thanks for the replies guys! Your info is very helpful. I think I am probably going to go with Bilstein Revalves and Hotchkis springs. I just hope the drop will not be too much more then 1".
