I guess it is a slight upgrade. More stopping power and less weight on the calipers than mine. Same exact size.

Twice the stopping power, supposedly boots right on and are the same exact size calipers as ours with twice as many pistons.

4 front 2 rears clk55 w208 clk 55 (2001)
2 front 1 rears srt6

Can anyone confirm this for me?
