Brake duct kits to fit aftermarket bumper?

dcs2k · 03-14-2013, 11:26 AM

Can I assume that any of the aftermarket brake ducts can be mounted on my new bumper?

I'm looking at Cantrell motorsports brake duct. Running on KW CS, and stock ZCP wheels. Appreciate any advice.

The duct holes are made in the undertray that looks to be blocked by the lip, so you might need to drill holes.

I would do one or the other. You'll probably destroy that lip trying to put brake ducts on it.

I agree with this. That lip looks too good to be putting holes in but with that you cover up the common duct mounting places. Maybe you can rig up a system that grabs air from underneath and directs it towards the brakes? Not ideal but may be better than nothing.

Perhaps fitting a NACA type duct underneath the splitter out of sight might be an option...

Here are some CF ones from an online search

Where do those outer inlets go?

thank you all for the suggestions. Im curious about using the NACA duct type under the lip. Any one on the forum using it currently? Will love to see how it matches up and a real life review if possible
