For 107s, Bilstein shows HD and comfort
 

Actually, it shows HD for the front and Comfort for the rear. Is that because of the weight of the engine? I really wanted HDs all around - anyone know the part number for that? Anyone ever use this setup and think "perfect"?

I went with comfort on my 300SD and quickly turned around and got the HD all the way around - a world of difference. Go with the HD, I think the cars weigh about the same. I have the HD on my 450 all around as well, better for cornering, a little stiff on bumps

I bought HD all around. I have the part numbers, but not with me. I will update in the AM.

Many thanks. The only part numbers I've been able to find are Comforts for the rear - I spent time on Blstein's US site and the International one.

The part number I have for the rear (Comforts) is: F4-B46-1184-H0

I bought my Bilsteins from the Adsit Company. They were able to tell me the Bilstein part number. They are great on the 560SL. www.adsitco.com
Good prices.

I apologize if I got your hopes up. I checked my paperwork and it seems that I purchased and installed the same P/N you quoted. I am happy with them.

If they come recommended, then I'll buy them.
