You are correct But it drives me crazy to see unmatched rear brakes. Brembo rear brake for the GMC 2019 will be a 4 pot system. Combined with a 8 piston front... the brakes will be so damn efficient. I run them on every vehicle I own... I typically get 75k before I need to replace pads. The 2 piece Rotors should last 100k. I have 120k on one set and still have tons of life left No doubt it’s crazy money, 8500-10k but if your looking for the “ultimate” system, this is the route to go. Not to mention your shaving 40% of the rotational mass compared to the original system... handling, acceleration, braking, everything is improved on that front. Only negative is your wallet will start smoking and you’ll end up working until your 80 years old. Should be epic Sent from my iPhone using Tapatalk
