At least from my current perspective we'll just have to agree to disagree.
Is your thinking the only thing stagger does is help you turn?
Then your correct if you don't turn you don't need stagger.
If the only thing stagger does is help you turn then the amount needed is totally dependent on the amount of turning you do.
If it's totally dependent on the amount of turning you do then banking has nothing nothing to do with the amount of stagger needed.
I think the last sentence is a true statement.
I'll back it up by saying the only thing banking does is allow you to go faster and in the turn you create more g force.
----------------------------------
Stagger would then need to be adjusted to changing g forces which have nothing at all to do with banking except that different bankings can allows you to go faster and make more g forces.
So, when banking increases while maintaining the same amount of turn or radius you will need to adjust stagger to compensate for the additional g forces. I think that's correct Al and thank you for your input allowing me to put the correct 2 and 2 together and get 4.
And it takes me back to my own original theory about tire surface speed and how increasing stagger increases the difference in surface speed between the two rear tires. When banking increases we've already applied more load to the rear tires. The increased difference in surface speed allows us to put the amount of slip needed to be fast back into the LR tire. If perfect then the increased potential to slip puts you back to what would be needed in the ability to slip or free up the LR tire, before g forces increased.
It means the amount of banking not only allows you to go faster it redirects how forces are applied to your tires.
Right now thanks to your incorrect thinking Al i'm pretty much convinced banking only should be looked at in terms of how it changes your ability to go fast in a turn, how it effects the amount of g forces you create and how weight is directed.
The above blended with radius will give you what's needed for stagger. That is except grip, tire hardness and air pressure along with sidewall flex need to be mixed in to.
... do you see it now Al? ...
