resipsa are you planning on taking it from the fang vents or undertray?

Fang vents.

My brake ducts are a modification of ModShack's forced air ducts. I removed the tubing from the air boxes and routed it to the wheel wells.

I imagine you could fit a NACA duct or some other inlet to the undertray but that would start to get complicated. Even in the case of the Nismo nose you could simply drill a couple of holes in the undertray and zip tie the brake tubing on top of the undertray and directly in the air flow.

I was thinking about this, but I have never seen NACA ducts drawing in air from under the diffusers, just mainly used to help dissipate heat from the engine bay. Anyone care to chime in?

Plus, NACA ducts only work in a laminar air flow field. Without wind tunnel testing (or careful track testing if you now how to do it), there is no way to assume the flow is laminar and not turbulent. Once the flow detaches, NACA ducts just don't work. Spinning wheels and tires are great at messing up air flow!
