4 Piston Big Brake Upgrade from 2019-20

So those bolt right to the knuckle without brackets? Or do they bolt to GMT900 brackets?

They bolt directly to the knuckle/spindle, no bracket required. They're a fixed caliper, not a sliding caliper

Awesome to see progress on this, sad to know they probably won't work with my LTZ 20"s.

Maybe I missed it when browsing through the threads, but is the A GM big brake upgrade that works for the 2003-06 rear disc brakes? It seems the rear suspension is much different from model-to-model. Anubody explored this already?

We're just working on the fronts right now.
We've had some successful test fits, constrained by 19+ silverado wheels, but no rolling installs yet reported here.
Mine will be soon, just waiting on wheels.
