Think I mentioned this already...but did the install on a 04 Avalanche and 03 Suburban with the exact same parts except rotors, used smooth rotors on the Suburban and its nowhere as good as the Avalanche.
GMT900 upgrade with smooth rotors is still a improvement over the stock GMT800 brakes...but I would stick with the slotted rotors.
I don't like how the painted calipers came out on the Avalanche, makes it look ricer. The Suburbans calipers are unpainted and starting to surface rust, they should be at least painted Black.
