Parking Sensors

[bikertwo]

Have just joined PH and would appreciate some advice. I have just purchased a Porsche Cayman and am having trouble being comfortable with where the front of the car is when I'm parking. This is not my first Porsche but maybe the bit of the car I can't see is longer on a Cayman. I'm thinking of adding sensors to the front, they are already on the rear, and would appreciate any advice and recommendations. Particularly a place to get a price and have fitted and I quite like the idea of the sensors hidden in the bumper without drilling holes.
