After replacing the factory tire at 50k miles and an alignment to verify everything is still looking good, I feel that my car does not handle as good as it did before I replaced the tires. I replaced the tires with factory Michelin's and I've had the alignment check multiple times (at 2 different places), but it still doesn't handle well.

Are alignment rack's ever re-calibrated?...or have a calibration period?

I have a '12 F Sport SE, are the camber/caster/toe specs different from a base model?

This is from the print out that I got from my 1st alignment:

Spec Range
Front Camber -1.0 to 0.5
Front Caster 5.1 to 6.6
Front Toe 0.00 to 0.20
