All the cars here in the Northeast have ice-breaker fins on their roof. It's very common. In fact, with the early snow we've had this week, I'm feeling almost naked without mine on yet. Not that there's anything wrong with feeling naked... just saying, safety first.

OP, those are some high-quality fins you found there. Are you going with the full rack? Have you considered putting a rack of fins on your trunk, too? Some people think that's overkill, but better safe than sorry, I always say.

 

Another mod that I'm not too sure about...rubber garage door insulator as front bumper lip.

 

Lol...me too. One is cool...anything more than is not.
