I think he is beyond doing a flip kit.

A flip kit usually nets about 6" of drop.

His bracket lowering is usually good for 4 inches depending on manufacturers. So combine the 2, and he is on the ground.

I see only 2 options here.

1. De-arching your springs for the drop you want, and using your adjustable shackle to dial it in. First I would run the bolts down a couple of notches. That way you build in some adjustments.

2. Put the factory hangers back on, and the so a flip kit.
