from my experience with springs, coilovers, and any other suspension mods, they do not provide alignment specifications. The main reason is it's personal preference if you want more turn in or less. Also how much wiggle in the steering wheel at freeway speeds.
All alignment shops will do are put the vehicle as close to factory specs as they can regardless of what you want. If you recommend or advise the shop you want something special they usually charge you extra.
My advise is to not worry about camber as the change in the suspension travel is minor (compared to a passenger car) and the biggest thing is the toe-in or toe-out is what causes premature tire wear. Make the front and rear wheels as close to 0 toe with you in the vehicle is the best to achieve the most MPG as well as give you a good balance handling. I was informed that Mazda likes to modify their toe a little hence the improvement in handling but also causes the tires to wear prematurely (This is my first mazda so going off of other people's input).
So in summary go toe 0 front and back, and keep your camber at -.75 to -1.5 is probably the most ideal. My experience is primary in suspension modifications on a Subaru STI, S2K CR, S14, AE86, and many other cars i've owned in the past.
