I would suggest DBA rotors (Disc Brakes Australia). They are a very popular rotor with LC80 owners around the world. Don't know who stocks them in the States (someone does because I've seen signatures elsewhere with DBA rotors noted), but a good place (probably one of the best places) to start on any LC80 set up is Slee Offroad. Christo there has been a longtime devotee to the LC80 cause in the States, and he stocks most LC80 specific things.

Another source of (extensive) LC80 knowledge is Jon at Gotham City Cruisers. If you can find that site, you'll find another library of knowledge.

cruiserman posts here from time to time, also. You can PM him, also. He knows his stuff, and will likely recommend you also try the LCOOL site. Can't remember the URL off-hand at the moment.
