Whats the difference between Bilstein HD's and Slp Bilsteins? I tried a search but didnt come up with anything...

 

its all in the valving. The HD's are good for stock springs, SLP's are valved for the SLP springs.

 

like what was already said, the slp bilsteins are valved different, and I believe Sam Strano said they where softer in rebound than the stock HD's, and aren't really up to the job.

I just put some HD's in my car I purchased from Sam 2 weeks ago, what a night and day difference between these and the stock deCarbons, even with only 45K miles on them. The car rides and handles much much better. I dare say it even rides better than my Firehawk with the SLP Bilstein suspension option, and it only has 6000 miles on it.

 

I ordered the Bilstien HD's from ws6 store and got the SLP Bilsteins... I was wondering if its worth getting them switched or if I wouldnt notice the difference..I am running stock springs..
