Tom,

my main puzzlement is [for an example] why does a ladder bar car work better at 2.5 degrees than it does at 1.5 degrees.

Is there something else changing other than pinion angle. I completely understand to have an additional degree of pinion angle the entire housing is rotated thus changing the shock bracket relationship and the ladder bar bracket relationship.

So is some mechanical advantage between the housing and attaching hardware coming into play? It is really not the pinion number that makes a difference but the housing to mounting points that finds a sweet spot?

You understand how some things with a race car "just feel right, or just feel better" My experience it in that area of slightly adding more pinion angle than would usually be expected and having positive results show on the ET slip and reported by the driver.

So what do you think is really happening?
