I think I'll start a notebook to track what I did and whether it improved things or not.

I'll drop the rears 1 psi to 35psi for next time out.

Next I need "Harry's Lap Timer" so I can video and analyze what I did that day.

I was hoping to get a lot more feedback but perhaps the racers are on other forums?
Is there a busier Racing tips forum somewhere or do the racers share no secrets in general?
Just trying to learn and am looking for more info on tuning tires.
If you are on the brakes as you turn (trail braking) then that explains the rear coming out. Trail braking does that, which is one way to get around understeer.
