I have that exact setup on my 300E. Textars in front, PBR Organic in rear, Zimmerman rotors on all 4. Stops AMAZING. It has a vicious bite if you hit it. Extremely powerful brakes.

My W126 can stop almost as well, but the brakes are "softer" on application. It has zimmermans with PBR Ceramic pads....30k on them and very little rotor wear and almost no pad wear!
