use thread lock, normally the bolts already have the thread lock on then like this

You could contact their customer services http://www.ebcbrakes.com/Index.html, or just go with standard rotor screws from yamaha, which look pish!, or you could get Titanium screws from Here, you can safely ignore the 'counter-sink' bit

and like Drewpy said 'thread-lock' is a must

thank's for the help guy's . as soon as the new pad's show up im going to bolt her up
