I will scrape my front chin spoiler on certain things (driveways that touch the road at a weird angle) and have bottomed out my undercarriage on crappy driveways.
The font chin spoiler (sport package) is made of flimsy rubbery material or thin plastic...it's not a big deal if it gets bent back or scrapes because it's black and you don't really see it..and it's quite flexible. The undercarriage...well... out of sight out of mind
