That setup is most likely going to rub, if you can I would return that setup before mounting any tires on the wheels so you can get a full refund and avoid and potential issues with returns. I have a 15x8 +28 setup with 205/50/15 tires. My tires already poke out. I am on swift lowering springs so I am roughly your height as well. My front does not rub but it is very close. The rear does rub at full compression. Making the tires stick out 8mm more would only make it worse.
