thanks, Jason - yes, I was banging through the gears, and there's now a =
steep 150' +/- DROP at this track, downhill turn, where I was in second =
gear at 7,000 RPM, first accelerating, then letting it slow me down as I =
approached the sharp right to the uphill climb.  I'm sure that did not =
do the diff any good.

Somehow the idea of putting a Subaru diff in this car does not feel very =
"vintage".

Question - has anyone checked the oil temp, and would cooling make a =
difference?  I do run Redline 75-85 gear oil.

I will report back and send carnage photos when I get it out.

Likely a costly and complex endeavor to say the least.
Knowing you, I assume you are using a quality oil already as Steve =

I notice you are racing faster lately and seem to be doing great with =
the car.

Begin Public Service announcement to all FoT...

That being said, (especially the faster you go) don't forget to remind =
yourself regularly about how you need to treat the drivetrain.
Perhaps most importantly on this issue is careful driving with a =
constant focus to smooth transition between the gears.
And really important is super smooth take-offs.
I'm lucky to have John Reed (best GT6 racer of all time) at the track =
with me most of the time.
He is never afraid to remind me of this.
And does so on a regular basis when I'm leaving the grid.
Even after all these years of coaching he will still often yell at me =
through my helmet prior to taking off.
something like....
 "Ride that F$#&%ng clutch baby!!"
or "Easy take off".
Wisdom I'm not afraid to admit I need to be reminded of in a tense =
moment taking off to hit the track.
One slip of the foot or abrupt start is all it takes to do damage to the =
differential.
I can trace most of my differential failures back to sketchy shift =
transitions or abrupt starts...
We all hate to admit that an equipment failure is our own fault but, =
speaking for myself, I know it often is.
This was an FoT Public Service Announcement...
