The important thing to consider is that where you put the sensor is the center of a three foot circle of coverage of the front of your car (1.5 feet from the sensor itself to the edge of this "circle of coverage")
Since I was able to put mine inside the slats of the grill, I was able to optimize the positioning so that the 3 foot circles created by my positions cover the whole front of the car with only two sensors.
If I understand you correctly, it sounds like all three of your sensors will be low on the bumper and will probably not cover the upper part of the grill/bumper.
Here is a pic with optimal positions on my S6 to get away with only two sensors as recommended to me by Tom at Bestradardetectors.com:

You should probably try to get them at least this high.
The sensors come with nice bracket, so although it is less than ideal, you could screw the brackets into the slats of the honeycomb of the grill and let the sensors stick out the front. That is of course probably unacceptable appearance wise, but it would work without visibly damaging the grill.
I have not been thinking about this stuff for a while, so I can't recall if it would be possible to mount the sensors behind the grill honeycomb without excessive interference. Probably not a good idea. I would ask Tom about it. He may have some solutions for you. I am not sure where you bought yours, but I think he is the US distributor, so he may offer support even if you bought it from another dealer.
