I have tried in total 6 different brands of brake pads on our truck, so far, none are up to the stock pad in terms of ease of modulation at the threshold point, or resistance to fade on repeted high speed stops.
Most of the aftermarket rotors are made in China. All rotors from there are the worst quallity porous cast iron. I just ordered new rotors/bearings etc for the fronts, I wouldn't even consider non-stock for these parts.
