I read this site a bunch, but don't usually post. I'm building a '94 DX hatch for ITA and I cooked a set of R4 pads on my first shakedown track day last Friday. I've been looking into brake duct options, but I'm unclear on the rule for poking holes, or where to have the inlets.

The car has areas for factory fog lights, but I don't think I can cut these out (correct me if I'm wrong). I can tie a plastic inlet "behind" the center grill, but can I cut it at all to facilitate mounting?
