I want everybody's old OEM shocks with 70-100K miles on them! I have KYB on one SLK after putting on Bilstien Sports. Both eliminated the suspension......turned it into an auto-crosser. Unfortunately I did throw the 180K+ mile old shocks away. If I hadn't I may have put them back on! Stay with stock shocks unless you are full boy racer. I will trade a set of Bilstien Sports with well under 5K miles for a similar set of stock shocks and throw in some cash. I'm keeping the original stock shocks on our second '99 SLK Sport as long as possible; 120K on it now and they are fine.
