When I was in the shop getting my car aligned and corner balanced, they asked me if I was interested in a brake duct kit. I said not until I have my BBK.
They were looking for a car to do the test fit to adapt their kit to. The guy wanting to do the work was the one who did the cage for z4mnyc, so he's very familiar with our cars (despite being a porsche shop). I'd be willing to let them use my car if there is enough interest.
Here is their kit for an E9x.
