Don, You are one smart cookie!
The biggest enemy to brake systems on race cars
is heat . By doing things like you did to your cobra
you improved the performance emminsly. I
would bet that you notice a radical difference in the
brake performance with the new ducting.
I.m surprised that someone hasn't made fiberglas
tunnels that would fit behind those small vents on the
front of the cobra. Aimed properly at the brakes they
would really do the trick for road racers.
