I ran cooling ducts from the stock bumper cut-outs without any problems (tho the passenger side was a bit tight). I used 2.5" x 7' replacement hose for a shop-vac and 2 approx. 3" x 8" attachment nozzles, plus a couple dozen zip ties, all for about $35 from Home Depot. Maybe it's ghetto, but it works and nobody sees it anyway!

 

I found a generic vent for marine applications that flows into a round outlet, which I may be able to adapt. I wish I would have worked it before the bumber was on the car though. The Aero bumper should really come with brake vents!

 

Sweet..the color looks great

 

Looking Good!!

 

No problems at all...~2 years now.
Depends on the quallity of work done,
but the non-OEM paint seems much tougher.
