Nice car Bill, a friend near me here has an 01 CLK55 with all the Kleeman stuff too and had their diff, but now I believe he put a quaife in it. He was breaking axles. That supercharger really packs a punch! nothing like laying into that pedal and having it shove you into your seat!
What did yours run at the track? Last November he got his fastest yet- an 11.09 @ 124.570
