Been searching all day on the RPF1 thread and need help deciding how big of a wheel I can fit out back without rubbing.

Front fenders are rolled and liners cut.
Rear fenders are cut inside to accommodate asm overfenders and rear bumper shaved.
Dropped 1.2in all around.

Going with 17x9 +45 up front with 235/40
Think i can do 17x10 +38? with a 255 or 265? They also list a 17x9 +22??


Thanks everyone.
