Michelin S9B slicks - any comments?

[captain jack]

Hi,

I believe Michelin S9B's were used in the Clio Cup series (19/57 15) and they are a medium hard compound? Has anyone got any comments as to their characteristics? Also, has anyone used them on a vehicle lighter than a Clio (950kg)?

I'm condsidering using them on my FWD racecar (750kg) but don't want to find that they are too hard!
