Slotted/Driled Brake Disks??
Well, it's time to replace the rear brake disk (well, the right one has too much wear(the mechanic says it is a typical Ford thing and we replaced the caliper). I'm not a performance guy, but it's be...

Do not bother with them as on the street it is just a cosmetic item and has no actual real use.
Sloted and drilled rotors where first needed in the endurance racing work. The reason was to add channels for off gassing of the braking compouds during repetative high speed and very hard braking rusulting in temperatures. These are temperatures well above what even standard street pads could handle without delamination of the braking compound from the steel backing. These are also cars that do not last an entire race on a single set of brake pads and they must be changed mid race. This creates the off gassing of binding materials used in the pads through the race as the binding matieral cooks out as the pad wears.
In a street environment even on a large vehicle, it is not needed as you do not generate the temperatures often enough to have brake fade due to off gassing of the compound or binding matieral. Most brake fade even in RVs and trucks are actually heat fade which drilled or slotted rotors will not improve.
Ontop of that I found that drilled and slotted rotors unless they are high end cryo treated rotors, they have a quick failure time in race conditions. I now run a better brake compound on my race car and OEM replacement rotors and no longer have to deal with off gassing fade and they handle the heat just fine.
