I run 215/45-17 Yokohama AVSi tires at about 38psi. Have same suspension setup as you; Bilsteins, ipd rear overload coils.
Slight rub at full steering lock, never happens during "normal" driving. No rub anywhere else with this setup.
I wouldn't bother with 205/45 tires, too fragile in the sidewall.
I'm about to drop my car with H&R Sport Springs, I'll post results here.
Bilsteins, Supersprint, K&N, Bosch+4, E-code headlamps
