Getting a alignment next week. Did some searching and found:

Caster L+4 R+4.5 // Camber L-.5 R-.5 // Total Toe 3/32

The car is used mostly on the highway and drag racing. Looking for best tire wear without sacrificing drivability. Are these the best setting for me?

 

Should be fine. Maybe use a bit less toe; .050" (about half of 3/32") is what I usually use.

 

Does it make the car want to dodge all over the road with very little toe?

 

Yes, with too little, it will wander kinda more than with more.

OTOH, with too much, it will EAT the outer edge of the tires.

The "right" amount works hand-in-glove with camber. Toe-in makes the tire appear to have less neg / more pos camber, by forcing the contact patches (bottom) of the tires together, toward each other, as they roll. The effect is very slight of course, since it only happens to the extent that suspension parts deform. But, the overall result is, if you run MORE negative camber such as for better turn-in, then you need to also run MORE toe to tend to keep the contact patch more nearly flat on the road, at the expense of increasing scrubbing across the tire.

IMO the best camber for street use is about -½/-1, the extra ½ on the right being there to tend to make the car track straighter on high-crowned roads. (same reason as the extra +½ caster split toward the right) And, the toe as I described. IMO 3/32" is more than necessary and only increases tire wear needlessly.
