Rim offset question for duster guys

I think I want to go with the 1 pc torque thrust 15's.

Front 15x7 -6mm

Rear 15x8 -18mm

I just want the wheel wells filled up and the front and rear tires to appear equal when you look down the side of the car.

I have disc brakes and am leaving the rear leaf springs in the factory location ( if that matters)

Will these offsets make the front and rear tires stick out equally?

Will I have trouble with rubbing in the front with this offset

Also, does this seem like a dumb combo?

Thanks
