Difference between s and none s
 

Though i did search before posting lol. I'm having some issue trying to find out the difference between them. Is it just programming difference or is there more or other options between the two. Thanks in advanced, Brad

Perfect and thank you for this. So the most noted would be the Race mod, electronic diff, brakes and tuning. Then what is the difference between Edition 1 since that can be purchased in both C63 and C63s? Body differences and interoir?
