hi there ,yes they are brembo , 8 pots off a merc sl 55 amg ( i think ) , the rotor size is 355mm x 36mm ap racing , rotors were chosen to fit inside my wheels (18" ). the caliper has a bolt on mount with bolt spacing of 110mm,i think this could be removed and the caliper radially mounted . no thoughts on the back yet , one bit at a time .
