Which is why I'd check the bushings at the tie-rods, steering knuckles and the upper and lower wishbones. If any of these joints are on the loose side, the transmission of power through the hub will throw camber and toe out of spec.

PS: I had a problem like this on my GTi. When The steering knuckle ball-joints were shot. They were so loose, that with a hard launch, the hubs would try to wrench themselves against the lower A-arm. As you'd expect..camber, caster and toe all went to hell.
Good advice. Have your front-end checked (i.e.: Ball joints, tie-rods and control arm bushings). Any alignment done to a car with a bad front-end is useless as the play in the joints/bushings will change the settings as you place diff. loads on the suspension.
If your front-end is tight then it could be a "radial pull". Try crossing the 2 front tires (right to left and vice-versa). If it pulls the other way you need new tires, or rotate them to the back.
