I've had the same problem, if the face of nut is worn at all it's been rubbing on the bell..
It can't be anymore then flush this the nut or it will touch particulary if the shoe is a bit worn.

What is your logic behind making the balls face the engine?
P.S. I grease the bearing every half hour of running, usually at the start of a club meeting and just before the final.
I have some syringes I use to put grease in, it works a treat..

only use 5x7 shims and for the crankshaft a thick shim made out of the broken bearing inner collar will do the work!

Finally was able to race my mtx6 this past weekend. Overall the car handled well, but needs a little more initial steering. The clutch is definitely different then past cars i raced. Not in a bad way, just the settings that work for most clutches does not work for this clutch.
I started with the nut flush as everyone suggested and after tuning it on the track i ended up around .7mm. The car still did not have the pop out the corners and it sounded like it. I kept trying to tune the spring by tightening and it was too heavy, then loosen and it was too light. After coming home i measured the clutch gap and was at .8mm when i thought it was set to .45mm.
Could having too much gap cause the lack of power out the corner? On the high speed section where i could stay on the throttle the clutch felt good.

Some times what looks or feels fast isn't, it could be when it really warmed up the engine came on tune and had a different power band and wanted to break traction.
I know there have been times when I thought I was quicker but the lap time was worse.
Could be your clutch setup change a bit with heat that would effect hook up too.
Maybe put the temp gun on your diffs before and after see if there is any change, maybe the viscosity decreases with heat. I wouldn't have thought a diff would heat up, but then again with the super thick oils 500+ If your inside tire is spinning I guess you could be loosing a pushing a of power through the diff.
