DR. DIFF 11.25 rear Disc Brake Kit

That's a different kit than the one most people have. This is the explorer based kit with the drum in hat parking brake.

The other kits, the 10.7 and 11.7 kits are based on the 94-04 Ford Mustang Cobra and have a parking brake in the caliper. I have the 11.7 kit and the custom parking brake cables, all of which are good.

This is the 11.7 Cobra based kit for comparison


All of these kits require you to make your own hard lines on the axle.

As to which one is better, it kind of depends on what your front brakes are, this kit is probably better with "stock" fronts where the cobra kits are great if you have cobra fronts (his 13" kit)
