It is, if you know the right people. Steve Foltz in Colorado has a fixture that he uses to bend the rear beam to zero toe. There is also a shop in So Cal that does the same thing.
Zero toe on the rear is the way to go for best handling. If your rear toe is not symmetrical, the axle may not be perpendicular to the centerline of the car. Maybe the trailing arm bushings are bad or the car was in a wreck.
Zero to slight negative toe in the front will help your car track better. As you drive down the road, the load on the front wheels moves the tires more toward a toe out position. Find an alignment shop where the guys know what alignment specs mean. Most of the guys in the major tire shops only know how to use the equipment, not what all the adjustments mean. A good shop will do the alignment with you in the driver's seat (or with the tech climbing in and out to check the alignment with and without the driver).
Toe has more affect on tire wear than camber or caster.
