hole centres on the mounting brackets seem about 1mm too wide for the caliper and hub carrier and the bolts get threadbound about 5mm from being tight, but they do pull in. rotors are super tight on the bells and take a lot of pulling on with the bolts.
I was told they don't give instructions out, and basically if i don't know how to fit em, i shouldn't have bought em. which is odd, because i fit industrial gearboxes and couplings, etc for a living and i've never had anything arrive without instructions detailing specs and tightening torques. SKF even include instructions for felt seals!
