First, thank you for your service!I'd love to see how they are holding up. Also, do you have a complete parts list of everything you needed for this? I'm interested in tackling this on my '14 RT when I get back from deployment.
Second - the simplest and most cost-effective way to do this in your case (since you have a 2014) is to just buy the big brake kit from Mopar. If you want to use aftermarket rotors and pads like I did, just buy the calipers, brackets, and pins from Dodge (look up Police Pursuit Charger 2014-2016), then get matching rotors and pads and you're set.
As for "holding up" I've already put several thousand miles on them and no problems at all.
