Jeff:

I thought the C43 was a 2 piston caliper and the E55 was a 4 piston. If that is so, I would be interested in upping to a 4 piston. I, too will look into the SL600.

I havent fully evaluated my braking needs and requirements. I plan on s/c my car, and would like to have at least a 4 piston caliper setup. If, the C43 is indeed 4 piston then I will leave them alone. Unless, of course, I feel the need to upgrade. Are the C43 2 or 4 piston?

I remember reading about your brake system setup. Weight saving would be ideal, and maybe someting to go after in the future.

Regardsless, keep us posted.

Edit: Ok, where did the 98 C43 get its brakes? E55 first arrived in 99, and on mbusa the 2000-2002 are 4 piston, not sure about the 99. The 99 and 2000 C43 probably did get its brakes form the E55. I gotta pop off my wheel and see for myself. Maybe I do have a 2 piston and the 99/00 has a 4 piston.
