It's not a concern on how strong the Nismo bumper is but more of do you want to constantly scrape the underside every single day. I was scraping the under diffuser daily on my stupid rolling curb after my swift drop. I had to buy a Bridjit curb ramp. I was not worried with the bumper getting damaged or torn off, but about the toll it was doing to my under diffuser. At the daily rate of scraping, it was clear I would have to eventually replace that piece often as it gets torn up.
It's a smart way Nissan did it too, that way you don't have to replace the whole fascia. But at $350+ a pop, it is still expensive.
