I went with Koni shocks. They are built MUCH heavier than the Bilsteins. They ride well, but control the car well. I bought my 300SDL new and was very disappointed that the Bilsteins on the new car didn't even last a 100,000 miles. I would think that premium shocks should last longer. I've had Koni's on two other cars and loved them. And, they never seem to wear out. They had a lifetime warranty on them, although that may not be the case now. Koni's used to be standard on the higher end (racing type) Porsches (have not checked lately) and are used alot in racing. I bought the shocks and then had my ind. mech. put them on my SDL. He had never thought about Koni's either. Since then, he's put them on other W126's. They are adjustable, also.
