Why is it that these are listed not to fit cars with performance package?

 

P30 performance package has 390mm brakes if so equiped. the pads are the same though as the calipers are functionally the same, but have longer ears to place the caliper farther out from the center of the rotor.

don't know don't think the E55 pads are the same as the E63. E63 and CLS55 were available with the P30 Performance Package.

 

Yes i have cls55 with 030 package and 380 rotors. Just doesnt make very much sense that they wont fit. Maybe something with akebono not approved for track use or something? As I only do street driving I suppose there wont be any issues though? But. Curios to see if anyone has a clear answer to this.
