Appropriate Wheel Offset for 18" Wheels?

Just did some measuring and my rear end is approximately 59" rotor face to rotor face. The stock rear end I believe was 57 1/8" drum to drum. That means my new setup sticks out 15/16" on each side or 24mm. Does this make sense? Will a 0 offset wheel work?

Holy crap! That's a lot wider if that's right. Yes, the stock rear end should have been 57 1/8". I didn't realize the rear disks moved things that much, you may want to ask Cass about that.

As far as 0 offset working, nope. If your measurements are right, you'd need a 24mm offset. to put the wheels back in the same place.
