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.

Looking at the picture it would seem like your tires are hooking up well. Of course only tire temperatures will tell you if this is true or not. What readings are your getting?

Secondly, I'd consider increasing the spring rate in the rear or dialing in more rear bar, if you have one. Unless you like driving with all that body roll.
