Does anyone know if it's the same one they use in the 09 LSD Dodge Challenger SRT8 ??

To the best of my knowledge, the 300 SRT and the Challenger SRT use the same diff from the W211, E55, and YES they BOTH get a LSD. I am not sure what diff is in the C63, so someone else here will have to chime in on that info.

See yeah
