What are the correct specs for a 4th gen drag car?

caster and camber

and should it have 0 toe or toe it in a little?

Camber should be -1 to 0* as much positive caster as you can run and like 1/16" toe in, that's at least how we set up our other f-body.

Camber was my biggest question

what are the settings GM reccomends?

I am in need of a good alignment and would like to get the most out of my car as possible.

The factory specs are not going to be the best for a drag car. And my wheels are sitting in a different spot than factory anyway

Don't know the exact specs.

Not as much caster, probably closer to 3* positive with -.5 to 0* camber and the same toe in like 1/16"

More caster will help high speed stability but will eat up tires faster because the tire rolls more on the corners of the tire then you turn the wheel.

Camber you'd want it as close to 0 as possible because you won't be hard on the gas or have weight transfered as much when you are street driving.

Toe in on either application is about the same, slightly in to offset the force pushing the tires out when you drive.

Caster is not a tire wearing angle. You are thinking about ackerman.

Caster is the tilt of the spindle forward or aft.

I think what he is trying to say is the amount of caster will cause wear on turns because of the increase of lean the tire will have.

Less I forgot, toe and camber are the only two tire wearing angles.

Exactly, 10+* of positive caster will not really be what you want on your 18" rim set ups and low profiles LOL.

For a drag car it's great.
