I have a gear diff from the second batch. filled with durango 1000cst.
It does feel smooth but at the same time it feels a bit to tight/heavy.

when turning by hand you can feel the teeth of the spider gears getting contact, Is that because it is brand new?

Is it because I use the 2 copper shims from the ball diff on each side? or do I need lighter diff oil ?

I only ran 1 raceday ( 6 heats of 6 minutes ). Do I need to give it some time? maybe after a few packs ?

any thoughts ?

edit:
Or is it maybe , that I used O-rings from Tresrey # TYS246 red o-rings
when installing those O-rings they were slightly to big, but I got them to fit and put the e-clip in the groove with a little force. Could they couse such a drag ?
