$2,180 on those GM parts sites online that kill you on shipping. Good news is the price they show is usually 5-10% over dealer cost. So if you know someone in the parts dept you can usually get the around that price without the expensive shipping charge.

Hmm did anyone ever figure out if the ctsv callipers fit? My brother just happens to have a set sitting on his shelf ahha

I installed this kit on a new Silverado a few weeks ago, very easy. Rotor uses the same retaining bolt to the hub, the caliper is an enormous 1 piece unit that uses the same mounting holes as the original bracket that the old caliper sits in...It is larger than the old bracket and caliper combined. Comes with new banjo washers, just transfer the original flex hose, bleed, and you're done. Gorgeous pieces.....This truck also got a set of 22" wheels, between the wheels and brakes, it was $7900 in factory options...

On the wish list now though............Haven't bothered to check out my staff cost yet...

I wish you could have taken some decent pics before you mounted them up.

There might be another factory swap option available in the future which should come at a much lower cost. It looks like the 2019's get much better 4 piston calipers, the rotor looks a bit bigger with more swept area.

They did change some things on the suspension of the 2019's, so there's certainly no guarantee these will bolt on, but it looks like they're offering the same Brembo package as an option and from a cost standpoint, it would make sense for GM to stick with the same mounting pattern. So there's a chance.... These things will be mass produced at an enormous level, so new parts from GM should be pretty cheap. It just might take a couple of years.
