On our 90x40' indoor carpet I am at 116/27 with a 5.5 and no esc timing. My motor and esc have been coming off cool, although I am pretty sure I could get a bit more oomph if I geared up a little.

Perhaps, try full rears for the 1/2hr, but full fronts for only 10mins.

The fact that you say the car is great after a few runs suggests you want to make the bare minimum of changes. Perhaps try standing the rear shocks up a bit more early on.

I've been struggling with rear grip lately as well. Some things I've tried with some success:
- only dope 2/3 of front tires
- add 1mm rear wheel spacers

Move front shock out 1 hole and go to 1 degree camber in front.

I think in your situation it would actually make it more tail-happy. It would allow the weight to transfer side to side too quickly and overload your tires even more; which sounds like what is happening. I would look at your downstop settings. Maybe try giving the car less rear uptravel to limit the weight transfer a bit.

Cheers
