BS to put it simply.
Tell me why it's BS? Lets hear it. I find it strange that you come on here asking a simple question about brakes that you don't know the answer too and then when I give you the answer and more, you act like you have all of this knowledge about brakes. :h
The lighter your rotors are the less heat load the metal can absorb. It's pretty simple really. I work on E450 busses and vans all day long and lets me tell you, I have yet to see a drilled and slotted rotor on any of them yet. The rotors on these busses are HUGE and heavy as hell. They are made that way to adsorb tons of heat without glowing red and boiling the fluid.
Rotors always absorb more heat than they can reject. The less mass you have the less heat load they can absorb. Drilled and slotted rotors have less mass and therefor can't absorb the same amount of heat that solid rotors absorb. Beyond that, slotted and drilled rotors have a bad tendency to crack. Not so bad on a race car because they are inspected after every race. But on a truck that tows an RV, that can be bad news and make for a bad day very quickly.
Oh BTW, no; my truck does not get 35 mpg. It gets 19 solo and 11 towing. :B
