| How do you figure? There may be a little more mass in the Big Brake Kit rotors,
but the cooling efficiency of the rotor is in the vein
design, not the mass. Once any rotor gets hot, it's up to
the vein design to cool down the rotors to a level where the
pads will still work. The advantage of the BBK over a stock
sized rotor is mainly the larger diameter rotor yields less
pedal pressure needed to exert the same stopping force on
the car due to the increase in leverage. You have to look at the rotor as a giant heat pump, because
that's all it does it reduce rotor temperature, allowing the
pad to keep working. I had on a set of Brakeman #3 pads
which run to a temp of 1200 degrees retaining a .48 coeff of
friction. They were still ultra grabby, no heat fade
suggesting the rotors were able to maintain a temperature
less than that of the pads. If this was not possible I would
agree with you & change to a different brake kit with better
vain design. But since the pads were able to continue
working & the rotors could keep dissipating the pad heat lap
after lap & not fade the rotors did their job & did it well. Most people have the problem where the pedal stays firm &
they have no stopping power -- this is an indication of
brake fade, where the rotor cannot pump enough heat away for
the pads to continue working, this was not the case I had. So far, I agree with Nixits suggestion -- looking into some
ducting to keep the calipers cool & will upgrade to the F1
brake fluid to cure boiling the brake fluid.
