Extended brake line question

[BendRunner]

Picking up the icon stage 2 lift on metal tech's BF sale. I've searched but have not found any definitive answer as far as extended brake lines go.

I am thinking about getting the goodridge kit, and replacing the rears when I have the lift installed and doing the other 4 when I upgrade to 5th gen brakes. Is the 2" extended line enough or do I need to go with the 4"?? Is the goodridge kit reccomened or should I be looking for something else?

I went with the 4", never know if you might decide later to go longer travel in the back.
