I'd say the fog light brake ducts are more for convenience, aesthetics, or rules compliance rather than maximum performance.  

If the car is dedicated for one-lap,  there's no rules dictating ducting locations, and let's face it.....  there's nothing convenient about the event.

Something else to go do some hunting around about, reading-wise is time-attack and rally front fender solutions for helping to pull air out from under the front wheel arch area.

specifically the aft part of the wheel well (instead of necessarily slapping vents on the fenders over the wheels)

What about minivan brakes?

If they're from an Odyssey (keeping it in the Honda family), they'd likely be a downgrade.  I think the problem with Odyssey brakes is that they were spec'd for an Accord and then used on a much larger vehicle.

Odyssey brakes are still quite large, and they still stop almost as fast as an Accord even with an extra 1000-1500lbs or whatever.  Like I mentioned earlier... all of the kinetic energy you are converting to heat has to come from engine horsepower at some point, and the odyssey has the same/weaker V6 compared with the Accord so its not unreasonable for them to be similar in size.

The #1 issue with Odyssey brakes is piston sizing (master vs. caliper), which makes them feel awful.

IIRC 4th gens use the same calipers & master, but a larger rotor than the 3rd gens.


But anyway... Odyssey is 5x120 which wouldn't work.

The brakes on the big Acuras are better than the Honda trucks. Specifically the Brembo calipers and big disks from the TL and RL. Aside from that, the aftermarket loves to help Honda kids spend money so they've cooked up all sorts of brake combinations.

TL-S brembo calipers and bigger TL-S rotors combined with a matching TL-S brake master cylinder.  those calipers will allow you to use much larger Evo 7/8/9 pads IIRC and retain the cheap factory rotors that make the setup so great on consumables.  here are the P/N's:

  • this all comes off a 2004-2008 TL Base 6spd or 07-08 TLS AT/MT
  • (factory part number) 45018SEPA60 TLS Brembo 45019SEPA60 TLS Brembo 90107SEPA50 X 4 (4 19mm bolt) 46100SDBA11 Brake Master Cylinder (make sure change the reservoir off your old BMC)
  • Centric Rotors (Blanks) TLS Rotors 125.40062
  • ARP Extended Stud
  • 7mm Wheels spacer that go in between the hub and rotors

Hey look, it's that conjecture i made  but in the form of ACTUAL USEFUL FACTS. This place is amazing.
