camber is part of an alignment
1. Toe
2. Camber
3. Caster
Toe is your biggest tire eater because it wears down the whole tire unlike too much negative camber that only wears the inside edges of the tire. Toe and camber are the only to angles that change during lowering. Toe is easily adjusted by moving the outer tire rod ends, camber is not adjustable what so ever on a civic. The main reason why camber kits are needed.
bingisSD adjsutable struts DO NOT affect alignment in any way, it's adjustable ride height springs.
Actually changing the wheel size will change the alignment slightly but nothing like lowering does. It all depends on the difference from the bottom edge of tire to the center of wheel. If there is a difference of 1" between you wheels now & the 17's then yes your alignment will be off, but not by much.
