When you take the bumper cover off you'll see that the stock beam is basically 2 parallel beams, the mod is cutting off the bottom beam. The JDM beam is basically just a strip of sheet metal. So the cut stock beam is definitely more sturdy. The airbag sensors are in the fenders ahead of the wheel well. With the JDM beam you should be alright in minor accidents. I had an accident at about 5-10mph with all the force hitting the right front corner of the car and the damage didn't come close to protruding into the airbag sensor.
