fading brakes & cracking rotors

i’m running 11.6" rotors off of a newer SHO but I have tossed the stock calapers in favor of the much stronger cobra calapers which I have modified to fit 11.6" rotors instead of 13" rotors that they were origionaly designed for.

problem #1 with hawk HP+ pads they fade due to pad hear very fast + blue rotor on the street. The don’t fade durring autoX but they do blue rotors so they are close to fading with these pads.

problem #2 The last autoX my car was at I cracked a rotor, I don’t mean the little stress cracks I mean a 1/8" crack that was about 3" long

solution #1 upgrade to track pads to solve fading brake situation.

solution #2 don’t run china rotors?

solution #3 go back to mushy stock calapers and track pads. the stock calaper sweeps the entire rotor where the cobra only sweeps the outer 2"
or so. overall braking performance comparing the stock ford pads on stock calaper on 11.6 stops faster and lasts longer compared to the cobra calaper with HP+ pads. The rotors hold up a lot better to the stock calapers due to the full sweep rather than having more clamping on the outer edge.

solution #4 get track pads for cobra calapers and bolt 13" rotors on car upon arrival at track. If i cord a slick while i’m there this would require me to swap hot brakes to the smaller size.

more details?

Lines? Fluid?

What type of rotor?

The answer isn’t always throw new money/parts at it.

try to find some better rotors i guess, as for the HP+ i mean yes they will fade but that was after i did 5-9 130-40 mph stops before i got any sort of fade. Use brake duct hoses (make sure you use aircraft grade heat resistant material or theyll just melt and be useless). i would go with the HP+ on stock calipers, otherwise like rx3 said i need to know where the crack was etc…

wow i completely forgot about this thread.

I have SS lines, I dont’ see how the fluid is relivent because smoking pads is not a fluid issue. usually motorcraft racing fluid.

I can’t run brake ducts there is no room I have intake/exshaust pipes in the way. The cracks start at the edge of the rotor (outer diameter) and a couple of them are about 1-1.5" long and big enough to fit a credit card in.
