It seems they bring some lug nuts which can also act as spacers, probably 1 inch.
As for the spindles, they should offer an option where you can actually lift the front if you want.
This way they should sell "front disc brakes with spindle lift" sort of, then for that price it would be a good price.
Forgot to say that in the brochure it is stated:
"This is a sophisticated system. We pre-charge every kit to save you massive 'break' (textual, sic) bleeding"

EDITED:
I just figured the disc goes behind the hub, the bolts included are to replace the existing bolts and to hold the disc.
I guess that this way the "for lifted kit" could be adapted to any kind of spindle...
