Quite a clever mod
I've been thinking about doing this, but then dremeling out the entire area inside the grille, but decided not to because it would be a f*cking tedious job to do!

I wanted holes specifically, because of all the typically Belgian splash from the newest asphalt in rainy weather. Thought it's suck in too much water maybe...
