What is your question?
Running larger tires on lowered vehicle would like better breaking power . Currently have single piston calibers would like to go to two piston caliber is the mount the same ???

You simply cannot just change calipers without considering the major functional changes of the entire rest of the braking system, including anti-lock brake system component differences and dynamic changes! This regardless of whether a mounting is the same or not.
The add on equipment you mentioned should not have compromised the factory brake system which IF operating correctly has all the stopping force that’s necessary for this vehicle. Perhaps there is another issue within the brake system that’s causing your concern - recommend having mechanic test drive.
