if you search through this forum there are a few threads on brake rotor/pad combo recommendations. After researching, I ended up replacing all 4 rotors and pads on my 2008 sport (at 40K miles, i had brake vibrations) with DBA T3 slot rotors and hawk LT pads, all bought from hawkpadsdirect.com. I've had them for just over 1500 miles now and love the breaking power, but the rotors are a bit on the pricey side. The DBA rotors have substantially more material than the stock rotors, I feel the stock rotors are honestly a little on the thin side for this size truck, but again i like everything to be over-engineered.
