Let us know how the StopTech kit works out after you've got some miles on it. I debated between trying that and going with the Centric slotted rotors and HD fleet pads. Since I tow a lot I ultimately opted for the latter since IIRC the TRD upgrades are basically relabeled Centric parts, and while I'm very happy with the brakes (especially when towing), even after 10k miles the pads are NOISY as all hell when creeping along slowly. At <5mph they're groany, not squeeky.
