Epic post!

I see your best run was with a 2.0889 (2.1) 60'. This is the key.

in my previous 5th gen Camaro life I was able to get (as I remember) a couple of 1.95s on stock Pirellis (SS) but My best on the Goodyear Supercar tires was 2.00s (1LE and ZL1). On my current SS runflats I have done a couple of 1.93s.

I know the Goodyears on your car are of a different compound (tread?) than mine were. They really are not made for launching and excessive burnouts made mine very greasy and the sidewalls are stiff.

Have you tried a very light burnout just to get the water off and then a street start with the nannies off where you ease out the clutch @ 2K then feed in as much clutch as the tires will take. I bet that is harder to do in the ZL1 as the power comes on sooner/harder.
