As far as I can see, for the 300 Base, and 300 C, the front suspension is completely different, spindles, upper and lower control arms, etc. Just different designs and parts, no cross compatibility, at least 2011 to 2011
EXCEPT the 2011 300 Limited, which shares many front suspension parts
The rear suspension seems to share most if not all parts, all versions of 2011 300
Pull up 2 different tabs at Steve White, select model in each, select Front or Rear suspension and compare
