The BMB kit is 235.00, no where near out of line for quality brakes. Don't skimp on brakes like
@Chris said. Its seems backwards and counterproductive for folks to spend hundreds to thousands on lift/tires/wheels etc but scoff at a couple hundred to stop it all safely.
I can attest to Power Stop brakes as I run them on my Silverado. I went with their extreme duty set up because I knew I would be flat towing my TJ. I have no stopping problems with the bed loaded with gear and towing the TJ. The best part of them is they actually improve as they heat up. You can go that route which is less expensive than the BMB but still not Autozone cheap,

There are some negatives to drilled rotors on off road vehicles, specifically getting rocks trapped in the holes. PS makes a different set without drilled and slotted rotors but I didn't see it when I looked.
