AX tire pressure vs. tread roll, kumho V710 Options

[mskala]

Question is this for autocross purposes: If I'm running 24PSI hot and the
tread wear triangles are still not touched, should I go lower? My thought
is that either:
1) lower pressure will improve the contact patch and more grip will improve my time.
or
2) lower pressure will make slaloms slower by having more flex/lean in the car which will increase my time.

Using Kumho V710 215/40/16 on a 7.5" rim on my narrow -6. 21mm torsion bars
in front and 180 pound springs in the rear, because that's as high as I want to go
and still be driving this thing on the street regularly.

Appreciate any input.
