Earl's brake lines, a good high performance street brake pad and a brake fluid with a high wet boiling point will give 90%+ of Brembo performance at a significantly reduced cost. Check out other similar systems from Baer etc.
I am on his side. There is NO need for SRT brakes on a non-racing version of the car. Unless you take your Jeep to the race track every day and you road race (not drag strip mind you), or you spend your time going up and down Pikes Peak several times a day, there is absolutely no need for Brembos for the average consumer
. Racing brakes like Brembos are great for combating brake fade and braking as late as possible in a corner at the race track under a timed test.
According to Jeep, the SRT stops from 60 mph to zero in about 116 feet. Impressive feat...but it is not all due to the Brembo 6-piston (front) and 4-piston (rear) calipers, and vented rotors at all four corners measuring 15-inches (front) and 13.8-inches (rear). Tires play a big role in the braking performance, as do the brake pads.

Proof is in the pudding...
"tires give out easy, minimal grip under braking
The moment you lock the brakes and ABS kicks in, the car is slowing down at a rate dictated more by the grip of the tires on the road, and not so much by the larger brake diameter and the clamping power of the calipers. Sure, the ABS logic also matters, but all cars have brakes that can lock.
This instrumented test has the 2011 Grand Cherokee V6 stop from 60 mph to 0 in 125 feet and I remember reading 124 feet for the 2014 model year, i cannot find the reference currently.

An 8 feet difference might make the difference in an accident, I absolutely agree. But I also am a firm believer that the average prudent driver can account for 8 feet of distance and work this additional gap in any following distance on the interstate or some other highway where he would be forced to implement such a drastic braking maneuver.
And don't get me wrong. BREMBO brakes are phenomenal for racing purposes. They have fantastic reproducibility, they resist brake fade and will stop from racing speeds much faster than regular car brakes, again and again and again
. But Brembos are overkill for cars that are not meant to go to the race track, like the Laredo/Limited/Overland/Summit trims. They make sense on the SRT8.
Also, between a 65,000 dollar SRT8 Jeep and a 35,000 Subaru STI, stock for stock, I would take the Subaru to a race track. And when it comes to increasing performance, for the same $1000 dollars spent, you gain more by modifying the turbocharged Subaru, weighing 2000 lbs less, than the SRT8 Jeep. At the end of the day, cars like SRT8 Jeeps are neither road going race cars nor something to take off-road over boulders. They are fantastic niche vehicles.
Just like for the Subarus, there are 3 types of brakes installed on the Grand Cherokee. The SRT Brembos (top of the line); the ORA-spec heavy duty brakes and the Laredo brakes. I already have the medium-spec brakes so I do not need to upgrade but one day I will look into better pads/rotors, but NOT Brembos. On the Subaru, I these days run HAWK HPS (front) and HP+ (rear) which dials a bit more brake bias to the rear (HP+ compound is softer than HPS). The downside is brake dust, but the braking feel is improved. A good brake fluid like the German ATE Blue or Motul is also required. Over the years I also used EBC pads and DBA (Disk Brakes Australia) rotors but I am done pretending I am Michael Schumacher and look for car parts inline with my life style and choices (married, mortgage etc).
