i don't know it came possible. the planets must have been inline or something. after to bolted up the calipers with the required spacers, the rotor is almost dead on the money. the rotors are only off center in the calipers by maybe 1mm.
HOOO make the beast with two backs!n RAY!
the only thing left is to buy brake lines and 2 more caliper bolt and 4 washers. i just have one bolt in each caliper now.
i'm probably going to do the single brake line with a bridge, rather than 2 from the master. cleaner
