The Caliper is the same, the pads are actually larger (taller) but still sit in the caliper. The brackets however are different to accommodate the larger rotor. You will also need caliper bolts, they don't come with the brackets.
I'd be more curious in fitting a 4 piston system to the fronts and rears. Would have to do some investigating. It turns out a lot of GM brake setups are interchangeable. At least with some of the newer platforms, guys are swapping 4 piston and 6 piston sets off Camaros, on G8's, Caddy's on Camaros, Corvettes on Camaros, etc, all over back and forth, which much bolting up. I might need to take some measurements and see. Would be interesting if we could bolt up a better caliper.
It does make a difference with the larger heavier tires.
Once lifted 03 Trailblazer on 35's, gave it up to travel the USA with my family.
