I don't know if this would be a good idea or not. Since there are no convenient places to mount rear sensors on the 350Z, I was thinking of making a custom bracket that mounts behind the license plate. The bracket would extend upwards and outward enough to position the two sensors as close as possible to the upper left and right corners of the rectangular indent in the rear body panel.
Anyone familiar with the 350Z would know what I'm referring to. The indent overhangs the license plate and underneath is where the rear hatch release button is located. None of the surfaces on the rear of the car are perpendicular to the road (everything is curved) so a bracket could be fashioned to provide the correct orientation. My concerns are...whether the bracket would be stiff enough to prevent vibration, how visible the sensors are (not very stealthy), and would the sensors be too close together? I'm even wondering if only one sensor would be sufficient. It might make the install be a bit less obvious.
Here's a pic.
I do think this would work in terms of protecting the car from rear shots...especially laser speed cameras which are becoming more common in Maryland. Radar speed cameras are actually being replaced with laser versions.
Anyway, I would like to get your feedback.
