The backspacing is the number flowing the wheel dimensions that are stamped on the wheel; 7.5J x 18 is the width and diameter of the wheel, the following number (ET 50) is the spacing.

The spacing on your rear wheel (original) is 52mm, the new wheel is 65mm. That means the new wheel will be 13mm closer to the center of the car. Thus, 15mm spacers will bring it back out to near the original spacing.

One other thing to consider is that the new wheels are wider. If the original wheels had the tire near rubbing, then adding width will make it worse if the new wheels have the same spacing.

Hope this makes sense, and helps!
