You might consider curb/object sensors, I don't know much about them, but I think it's kind of like the rear "back up" sensors. My biggest concern with a aftermarket spoiler is the awful transitions for the entries to parking lots, etc from the streets/roads. Some are difficult w/o the larger spoiler and if you lower your vehicle at all it will almost be impossible. Stupid road engineers, don't they know that Mustangs have to be lowered and equipped with awesome spoilers?
