James Lopez, I have had ceramic pads on my 2001 Yukon Denali for over 27,000 miles, and I would almost say that the ceramic pads have increased the life of the rotors. (The rotors are still within factory tolerances.) I do not have a benchmark for non-ceramic pads on the Denali; so, therefore the reason for my hesitance at making the comment about increasing the life of the rotors.
Getting to the point of this thread, I also have the ceramic pads on my Coupe, and the improvement in braking is around 10 feet shorter stopping distance from 60 - 0. I have no regrets about installing the ceramic pads. Going with the drilled and slotted rotors is a personal decision. If there is a warranty against cracking, then it gets more persuasive to go with the rotor swap.
