Re: Anyone have slotted rotors? Need info...

["RoccoPhil" <roccophil@mindspring.com>]

Don't mean to be a poop here, but remember that the more surface area you
take off the rotor, the less braking material you have for friction.  At
some point you begin to hurt your braking system.  I have PowerDiscs with
the Atom figure and the best I can figure is that the rust that sits in the
groove is what makes the pattern visible (I guess that because I have yet to
drive the thing as I am still in overhaul mode).
