Maximizing caster is best for big end stability and reducing wandering.

Camber is kind of the odd man out since a huge amount of negative camber can reduce rolling resistance (like skinnies) but at the expense of terrible inside edge tire wear. I'd just run the normal amount of negative camber, say 0.25-0.5 degrees.

Toe is best set at a miniscule amount of toe-in for highest trap speed. Theoretically 1/32" of toe-in should flex to zero toe on the big end. As you get closer to zero toe you get rid of the self-canceling effect so be careful when street driving.

A hidden suspension optimization we need to consider on a drag car is bump steer. If a car has a ton of bump steer, it essentially puts the brakes on when the nose lands because of toe change. Minimizing bump steer can net you a few thousandths...

Ahh, sorry. Positive caster. Upper ball joint behind centerline of lower ball joint as far as possible. Factory arms are good for maybe 4 degrees. Our arms increase that to 6 degrees or so...
