275/30 street tires (ie. PSS, not Cups or AD08R etc) on those fronts will fit without a single issue, even if dropped hard.
Rear you can use a 285/30 and be fine as well. That fitment is awesome for E9X M3s.
For comparison , I am running 10" ET8 275/30 in the rear and I have no rubbing on H&R Sport Plus. Your setup would have 4mm more clearance to the fender, offset by +5mm extra tread with a 285. So it will fit virtually identically.
