I am in the process of getting our DD sfi approved as we speak. It will be the 1,1 2 rating which means they are cutting one setup apart and spinning the other to 8500 RPM's. These clutches that are being tested are exactly the ones we have sold from the beginning. After approval all the DD will be engraved with our SFI #. I will check whether or not a certified certificate from our company will work on the ones that do not have the #'s engraved. If not then the clutch will have to be sent back to us for that to be done. I would think a certificate would be accepted. Can you check on that Gene?
