that is were I typically start for Florence, Lawrenceburg, and Moler which sounds like the area you will be racing.
The problem with the LR being ran low on pressure is that they build heat faster and expand, rendering your stagger numbers useless. also with the left front at 8, I think that is too low, makes it hard to push a car with flat tires, and you get a lot of sidewall deflection, which will make steering feel lazy, or spongy. It also will soften wheel rate of that corner.

Do these pressures vary with track surface Temps ?

[JustAddDirt]

not for me no.
might adjust for track conditions slightly

[Bob Hubbard]

Thanks that worked .... Now that the old car is handling better ....The New car is ready .... LOL

[Bob Hubbard]

This might be 2 questions .... We have one set of shocks we can adj by air pressure & another set plus 2 from the chassis builder .... The extra 2 are for adj to track conditions .... Is this doing the same thing two different ways ? ......The adj shocks were for are old car ....

gas pressure would be a small compression adjustment. Typically a rough track adjustment.
Gas pressure should be the only adjustment on shock. Any other kind of adjustable shock would not be following the rules set forth by UMP, AMRA...etc.
more than likely if they are valved slightly different for heavy to intermediate
then a slick track set.
