When I installed my H&R's I got standard oem Bilstein shocks installed on the front at the same time and left the SLS on the rear.

There are only two Bilstein shocks for the W126, standard or comfort and HD. There are two Konis also, the yellow and the red.

Depending on who you talk to you will get answers but I am happy with my stock shock performance.

I also have #1 pads in the front and the original pads in the rear, not sure what they are.

I have just fitted a camber kit to the rear so I can now adjust the SLS lower without having to worry about negative camber. I have 1 degree negative in the front which is just enough to feather the inside edges and require rotating every 12 months to prevent excessive wear on the inside edge ending tire life.
