Combine our BIG MOUTH ram air kit with our stage 1 brake cooling solution and you have a potent track oriented performance package for your 2013-2018 Ford Focus ST.
Give your engine the air it needs, and keep the brakes cool.
Comes with all stainless hardware and endless color options.
Stage 1 brake ducts were track tested with on-board rotor temperature diagnostics, samples taken at 12 Hz using infrared thermometer and data acquisition during racing sessions. Driven through hundreds of racing sessions under extreme ambient conditions (Arizona motorsports park and Arizona Wildhorse pass, ambient temperatures in the 100s) . Before and after results were recorded as well as a lot of positive driver feedback. Data indicates that the rate of heat rejection is (slope of the temperature vs time plot) improved greatly (observable slope), as well as maximum rotor temperature and transients (cooling immediately coming out of turns).
If you need brake cooling for your 2013-2018 Ford Focus ST, you found it.
All testing done on the same day, on the same stretch of road with the same driver.
