Akebonos vs Upgraded BBK

I don't think it would be too terribly hard to rig a ducting system that blows air directly onto the brakes. Doing a quick google search comes up with a lot of nice custom-fabbed setups that look fairly easy to make. The most time consuming part would just be fabbing flange mounts and making sure you've got proper clearance.

Into the wheel well isn't going to be enough, has to be close to the brake rotor as my big *** wheels seem to block any passive air flow.

Travis had a custom kit made. Stillen is supposedly working on one (they have it on their press car) but any emails to them have fell silent.

I recall looking at Travis' log but he never extrapolated on the design. I'm not holding my breath for the Stillen kit as 1) they'll make everyone buy their fascia and 2) it will require plenty of labor, cutting, and redesigning to make it fit most likely (given how their other parts usually go).

The main problem I noticed when looking at the car with the fascia off is there are three options for getting air to the rotors if piping from the fangs. You can cut through the wheel liner and hope you don't have clearance issues with ducting in the wheel well. You can cut a hole in the bulkhead to pass the ducting through but you'll never get a 3" tube through there without some serious cutting. Finally you can route the ducting under the bulkhead and then back up, but you'll have ground clearance problems and have to cut or remove the underbody cover.

I'm leaning to a NACA duct pickup right by each wheel much like Modshack posted a while back on his Audi. My goal would be a single unit that bolts on with one or two bolts and can be easily removed when not desired.

I looked at it closely when I installed the oil cooler and as I remember there were quite a few openings but unfortunately they were all on the small side and would need to be enlarged. Probably the easiest route is through the fender liner, there should be enough clearance from the wheel if you route it carefully. You could even reduce the duct size at that point if necessary.

The main thing that I'm looking for is a metal duct outlet for the wheel hub. I don't have any equipment for welding so making this part is more or less impossible for me. The rest of it I'm sure I could hobble together from off the shelf parts.
