Bikes: 1982 Trek 930R Custom, '91 Diamondback Ascent w/ XT, XTR updates, Fuji Team Pro CF road flyer, Specialized Sirrus Gravel Convert, '09 Comencal Meta 5.5 XC, '02 Marin MBX500, '84 Gitane Criterium bike

those are Basic Avid rotors, and are not "too big".
the wavy circumference is to reduce squealing.
i have never seen a "165mm" rotor for bicycles, EVER.
there are 140, 160, 180, and 200mm rotors available, and i've seen a couple 203mm rotors too.... and there are some overkill 223mm rotors out there too...
the biggest things i see with caliper mounting errors are getting the adapter mounted in the correct orientation, and trying to use the wrong mount, entirely.

sidenote: RIM brakes on bikes are actually Really Large diameter DISC brakes.
