Exactly why I said that all of the increase in stopping was a result of the pads and not the rotors. The only time slotted/drilled rotors help you stop more than stock is:

1) If the slotted/drilled rotors are larger in diameter than the rotors they replaced, or
2) The vehicle is being raced and the rotors are being heated enough to fade

Since we already are running extremely high-quality Brembo blanks on our GM Trucks, replacing stock rotors with any kind of slotted/drilled rotors of the same diameter actually DECREASES stopping power due to lessened surface area.

Anyone thinking about slotted/drilled rotors the same diameter as stock should look at it as a completely cosmetic or appearance upgrade, not a performance upgrade.

 

I didnt say that it was the rotors OR the pads doing the better stopping job.. I simply stated that the combo of the two upgrades helped out a lot... I did notice WAY less brake fade with these rotors which has to be from them cooling more effeciently.
