Having just done this , there are three points to note .... 1st , Brembo parts use a 12mm bolt ( so you have to use TWO sockets , 12 mm + 13 mm ! ! ) ... the countersunk bolt is T 30 Torx ( not Phillips as the footer suggests ! ) .... Brembo parts are a few £££ more , but they paint the discs tungsten grey ( so they do not need degreasing ....and... the ventilation slots do not get ( horribly ? ) rusted over a few years use , like slightly cheaper discs ( think MOT tests etc ... ) ...hope this is of help ( ? ) ...
