Brake ducts...do they really make a diff?
I found crooked willow web page and they have these very cool looking brake ducts....anyone have any experience.
Under what conditions would it work the best? Auto X, road racing?
Also, if it does work how do you instal in a stock bumper setup?

brake ducts
Thanks for that reply Gordon! I had the same question. Sounds like I'll need to install a set of CWC brake ducts next season. With the heat issue being addressed with the incoming air, I could use Hawk HP Plusses instead of the Hawk Blues (expensive and heat-checks rotors!)

Do these really work that well on track? Not meaning to doubt Mr. Monsen, but I'd like other opinions on the product.
In looking at the pics on CWC's website, the air appears to be routed straight into the center of the rotor, NOT into the venting fins of the brake rotor...

Every effective brake duct I've seen routes cooling air onto the brake rotor venting fins.

they don't hook up to the front bumper at all, so no problem there. the work very well. they pick up high pressure air from inside the wheel housing. they work so well that you have to heat up the brakes a good bit or the brakes can get too cold. -gordon

I have the Crooked Willow ducts, using the stock brake system, Hawk Blue pads for the track and R1 lip. It's hard to quantify just how much extra cooling they provide. I should have used temperature measuring paint to measure temps before and after the install.
Anecdotal evidence: I've had no brake fade from hard track use after installing the ducts. I perceived minor fade before the install. Also, I had unusually high pad and rotor wear after a track day run in cool temps indicating my brakes were probably too cool and the ducts should have been taped closed a bit. I ran an event in colder temps before installing the ducts and didn't have this problem.
To sum it up, they provide "some" extra cooling.
BTW, the air is directed into the "eye" of the rotor, through the cooling fins to the outside of the rotor. The duct also protrudes into the airflow much better than the stock sytem, actually outside the width of the tire.

I'm not sure about softer, but one of a lower temp range possibly. The Hawk Blues are very abrasive if they aren't up to their designed temp range. Once up to temp, they're not bad at all. You could try another pad for cooler track days but it would take some experimenting. I'll stick with the Blues in cold temps for now and just close off the ducts a bit.
