DRL's to Brake cooling slots.......
 

So, has anyone with a '13 given thought to removing the DRL's in the chin, and somehow fabing a duct into the wheelwell?

I'm seriously thinking about it...... on the face of it, it seems doable.
It's almost like they had that in mind in the first place.

You could start with the kit from Stillen. If I had that bumper, I'd personally keep the DRL's and route the ducts where Stillen has them.
