MK7 GTI Brake Cooling Deflectors

thingiverse

Brake deflectors for the MK7 GTI that mount to the lower control arms and blow air onto your front brake discs to cool them. With these, the stock Performance Pack brakes and Motul 600 fluid, I didn't experience any brake fade during a track day at the Charlotte Roval. This version was printed in ASA plastic and after a track day and a few months of driving with them, they're holding up great. A previous version was printed in PLA, but those warped badly after a different track day at the Roval, so I recommend ABS, ASA, or another high temperature filament. Another benefit of using ABS or ASA is you can make a glue by mixing some filament with acetone, and that can be used to bond pieces together. The stl with assembly in its name shows how to assemble the pieces. Finally, the two pieces with pin in their name will go through holes in the lower control arms and will be attached to the deflector using a hex head M4 screw with a nylock M4 nut. Pictures are included to show assembly of the brake duct itself, as well as how to mount it to the car. 100% infill should be used for all the pieces with "Brake Duct Mount V2" in their name, but 15% should be fine for the rest of the pieces. For the pieces with "Air Scoop" in the name, the .full version is preferred, but I was having some issues printing that in ASA without an enclosure, so the .top and .bottom pieces are included so those can be used instead in that situation.
