Been thinking a lot about this. Aero fascinates me and I've been googling to figure out more on how it all works. I would imagine tucking the exhaust up high enough to allow a flush undertray would be the hardest part right? You could come off the pinch welds and go straight across i would think (but the rear subframe would still stick out past the undertray, would that basically defeat the purpose? Or does every little bit help?
