Upgrade Braking

I would like to improve the braking of my Demon.
What would you recommend?

All depends on how big your budget is and big your tool box is. Doctor Diff is the best place for the average Mopar guy to get brakes. He has mild to wild brake kits and all of his stuff is tested and proven. I've used a bunch of Doctor Diff kits over the years. You can also read up on Mopar brake kits and options in the B body book I wrote a few years ago. https://www.amazon.com/dp/1934709301/?tag=joeychgo-20
