you have more flexibility on an ES than an MSP...in my experience anyway. i know i can get almost 2 deg of negative camber on my ES...IIRC, the best you can do on an MSP is .8-1 deg.
I had the dealer put the Mazdaspeed alignment on my car (actually the suggested alignment of other MSP owners) and it made my car DOG SLOW. There was just too much toe out.
