while Michelin does not disclose the exact differences they are different. Michelin also claims they should not be mixed and matched. I have known several people who have went against Michelins recommendation with littel to no ill effects but, I have also know people you claim the M0 version does not hadle quite as well as the C1 version. Looking at the two applications the logical conclusion is that the Viper version would handle better while the Mercedes version would ride nicer. We have never tested the two versions head to head so, there isn't any concrete evidence to support that supports or refutes what I have heard ....
