999 front clutch clearance with 6 frictions

With four frictions, I still like to keep it looser. With five or six frictions, I'd drop it down a bit too. And if it is a little loose and you get a 2-3 shift flare, you can readjust the kick down band tighter.
If you do not have lot of spring in the clutch retainer, the looser clearance is a slight bit safer from what I have read and experienced anyway.
