B6 is the "heavy duty" valving. B8 is the firmer "sport" valving. It's personal preference as to which you run. B6 is "softer" than B8.They've got 2 sets though, B6 for stock cobras and B8 for lowered ones. Does anyone know, are they the same length shock and just different valving, or are the ones for lowered cars shorter shocks? Just wondering which would be best with the sport rear springs. I may trim them enough to drop the car an inch or so, so I'm guessing the B8's are what I want.
