The G2 CORE BBK gives your lifted Jeep JK, with oversized tires, the braking power it needs to safely stop and be in control in mild and emergency braking conditions. The oversized rotors (front and Rear) with the larger caliper brackets, extend your OE calipers further from the centerline of the wheel and create more leverage to increase the stopping power.
The oversized rotors are slotted to improve heat dissipation and allow for more surface contact with the brake pads. The Performance Brake pads are rotor friendly and dyno tested for maximum performance and service life.
I had my doubts, but after installed them I went for a ride and it is a big difference, I'm running 35" on a 20, and I had a hard time stopping with the stock brakes, this is a nice inexpensive upgrade.

Got a great deal on these, they have worked flawlessly and they helped my stopping distance by about 17% less... so well worth it when you are running 37 inch tires.
4.0Good Value, Inconsistent Machining
These are a good value and did improve braking power (but not brake feel). So far I installed only the front and think that braking performance improved about 25% - for the same amount of pedal effort, Jeep stops about 25% more forcefully. I'll probably do the rears once I need to change pads.
However, be aware that the machining of the caliper bracket is very inconsistent. One side was fine, the other was clearly out of spec and I had to do some serious filing of the metal to get the pads to fit. You should also file (dramel) excess paint around the bolt holes for a flush fit.
The rotors and pads are generic Centric/Posiquiet - nothing special.
There are no installation manuals - but you can download the Dynatrac Progrip install guide - it is the same thing.
Also, on my JK right front the brake lines are on the edge of being too stretched with the caliper now being an inch further from center line of wheel. I think I'll have to free the brake line bracket and tug it 1/2" to the outside.
