265/35-18 is way too short. 265/40-18 is about as short of a tire (at about 26.3" or 26.4" tall) that I'd ever consider for a S197 for everyday, normal driving. At 265-wide, it's also about the widest I'd really want to put on 9.5" wide wheels (for other reasons).
You're stretching those 245/45's a little. Being only half an inch above max recommended doesn't bother me, but having visibly more sidewall up front than out back does get my attention enough to ask why. I don't think that lowering by itself can visually fix this sidewall height issue.
'08 GT coupe, 5M, wheels, tires, pads, fluid, a few suspension mods . . . finally lowered (all of half an inch)
'10 Legacy 2.5GT, 6M (hers) . . . '01 Maxima 20AE, 5M (spare, winter driver)
