Already huh?? Even though it won't rust, and the car chasiss is kind of stiff... I will still try to avoid the scraping. What kind of scraping you usually encounter with?? See in Normal front engine car, the exhaust (especially aftermarket one) would be the first touching the ground or else it's the Front lower spoiler or at the rear it will be the muffler... But on the NSX, you don't have anything underneath to alarm you that "you are there"...
I will still slow down and try to maneuver it instead of let it scrap...
