good write up. worth noting is using a bolt/nut would mean going down a size so it fits? or just a longer bolt with a nut aswell?
and it seems the fact the pedal is harder means theres less fluid area (force) being put to the pad compard to the standard one wich in turn will over heat the rears.
and the tru test is to get them red hot (literally) a few times and see if they crack
