Barracuda Ride Height?

Hyup, get the front end dialed in first. Get your alignment guy to cycle the suspension up and down, to see what the camber change is doing. If you happen to set your height too far from stock, your camber will change over every bump and pothole. Any camber change, changes the toe-in. And changes in toe-in lead to wandering, or a nervous hard-to-drive feeling, and/or a car that likes to follow "ruts". So get the front end dialed in first. Of course, the rear has to at least be close, as you are doing this. The closer to level the car is, the more caster it will have. Jack the back up and watch the caster disappear. This is fine for a streeter, but caster is nice to have on long road trips, not to mention at the big end of the track.
