New GTR Size wheel question

[sixmassive]

Looking for new wheels for my R33 GTR. i'd like to fit 18x11s. 295/30
Offsets between +15- +18. I do not want to roll my fenders, But i dont mind a little rub on full lock. anyone have experience?

Car is lowered on JRZ suspension, but not tucking tire

No much info out there on 18x11.
All i've found:
