The math seems odd if you're not familiar with wheel and suspension geometry, but you'd be looking for ET22 (37 - 15).

Positive offset is a measure, in millimeters, of how far outboard the wheel mounting face is from the wheel centerline. Adding a spacer moves the mating face farther inboard so you subtract the thickness of the spacer from the wheel's manufactured offset to determine the new offset.
