Casually reading through some threads about brake cooling and noticed that an issue popped up was how to install brake ducts for bumpers other than the ones Stillen is pre-made for ('09-12 factory bumper + Stillen facia) or Nismo (RC or copy thereof from Synergy or Finite)
I have a 2015+ Nismo. There's no off-the-shelf solution for hooking up brake ducts without hacking up the bumper for some universal ducts.
For a race car, no problem:
Doesn't look half bad
But is there a solution without hacking?
Then I found this thread:
Nismo bumper brake duct install
Basically, this dude mounted some NACA ducts on his Zspeed undertray. Wicked solution
However, when i see the 2015+ nismo zspeed tray, it has this dip in the middle:
So i was thinking?
Why not cut a couple holes as pictures here:
Rivet on these:
Connect the hoses, and viola?
Could even put some mesh in between the opening and the flange to block rocks
conceptually . . . would that spot pick up enough air to be worthwhile?
