It's definitely worth the upgrade. Much better brake feel and a pretty good amount of additional braking power. I used the police package calipers for a 2008 tahoe and for pads and rotors just go with your preferred brand. Make sure you get the calipers WITH the brackets (most come that way) and not bare calipers because you need the new brackets to make everything fit. Pull off your old pads, rotors, and calipers. Put the new rotors on, bolt up the new caliper cage, put the pads in the cage (the pad with the rounded inside radius goes on the outside the pad with the straight inside goes on the inside), slide the caliper on and torque everything up. The only modification I had to make was to relocate one of the clips that holds the brake hose/abs wiring. There's a threaded hole on the top of the knuckle that you can bolt right up to and it should all work with minimal fuss. VERY IMPORTANT: You MUST have 17" or larger wheels to clear the new caliper package. Also consider replacing your spare with a 17" if you don't already have one (a 16" spare will still fit on the rear but who want's to have to change two tires if you get a flat on the front).
