Thanks all for your response. Reason why have considered the Billy B6s instead of the B8s is a conversation I had with Bilstein. Their recommendation was to use B6s with coils that drop 30mm or less and B8s with coils that drop greater than 30mm. The BMW performance coils drop 25mm from stock (not sport) coils.
