If I didnt have a chin spoiler I wouldnt worry about it scraping at all on stock ZCP suspension. However, I'm lowered and have a chin spoiler so I guess we will have to see.
I normally drive pretty much the same routes everyday so I know where my problem spots are and I just need to avoid them or be careful. I drove to work this morning without any problems, so 1/2 day down, many thousands more to go lol.
I will say one thing, it is on there pretty good... so I can totally see me damaging the mechanism and track that moves the plate, but I dont see it getting ripped off (at least without some effort). Damaged to the point where it doesnt work is probably the more likely scenario... then back to the drawing board I guess.
