New aligment specs.. still feels vague

Disagree... camber should not be positive for radial tires. But I think the ride height is a significant issue. I run 215/70-14s with the front DROPPED 1/2 to 3/4 inch from spec.

IME 2nd gen. Barracudas are very twitchy on the freeway if they have a nose-up stance -- it's aerodynamics. Get that nose down.

I'm curious what .13 degrees works out to in inches of toe... Offhand I would guess it's not that far off...

Yeah the toe is just fine. It's a little less than 1/8" toe in.

Here's a calculator that can be used to convert from degrees to inches of toe. Just needs the tire height and the angle for one tire. It assumes they're both the same angle, so in this case I entered .125* because one side was .12* and the other was .13*.
