Basically new Brembo M50 takeoffs from a 17ZX10R so they are 100mm takeoffs due to a superbike build bike had 17 miles when removed . Also have a brand new Brembo RCS 17 in the box this is the perfect aftermarket MC for these calipers per Brembo. $600 TYD for everything. Text me for pics 973-997-5369
