UPDATE: Available now!


http://www.boombaracing.com/2014-fiesta-st-brake-cooling-deflector/


We finally feel like it is time to let the cat out of the bag.

It is no secret that because of the torque vectoring, these cars like to heat the brakes up quickly.

We decided it was time to fix this well-known issue. Our goal was to make a piece that did not require to you make unfavorable cosmetic alterations like removing fog lights as you have to do with some of the competitor kits on the market. The plan was simple, we wanted to make something that worked, but was also discreet.

Pics/pricing will be coming out very very shortly.



---Pics added---










To heat up brakes, car was driven on a closed course and the brakes were aggressively applied to quickly slow the car from 40 mph to 20 mph, the repeated until the target temperature of approx 500F degrees was reached.

For cooling, the car was driven on a close course for 1.5 miles at 40 mph. First to obtain a cool down temperature as a result of natural heat dissipation, and then repeated with the brake deflectors installed to channel fresh air onto the hub assembly.

Where does the air come from? I honestly don't see these doing very much at all without a high pressure source that forces air from the front bumper. The turbulent air inside the wheel well won't cut it IMO. Porsche has a similar duct design but still have a vent from the front bumper to allow air flow to the brake guides.

Nice, looks like your dust shield protects the lower ball joint...which the OE dust shield does not.

Any chance these dust shields would work with a BBK?

(is that a FoST?)

Looks like the dust shields are in place during the smoke test video.
That's a bummer, since now two variables have changed between "stock" and "boomba". How much of the difference is from removing the dust shield vs. the air deflector.

The first "stock" number, is that done with the stock dust shields installed?

In the data posted above, the "stock" numbers are tested with the brakes completely stock [no deflectors and the are dust shields on]. The "after" numbers are with our deflectors installed and the dust shield removed. The video may differ from this.

The difference come much more so from the deflectors because even if you were to take the dust shields off when stock, there still would be no air flow without the deflectors.
