Jim,
Drilled rotors are one of those incremental improvements. Taken
alone, they don't do much. They tend to crack around the holes if the
holes are not chamfered properly. Yes, they are effective in reducing
fade, but unless you routinely fade your brakes, they simply look
cool.
There is a conversion that uses the vented rotors from a Toyota sedan
that would give you more cooling and greater rotor mass. (More rotor
mass=larger heat sink=less fade)
If you are experiencing brake fade, the simple fix is to remove the
sheet metal backing plate from the upright. This made a world of
difference on my rally car years ago.
