I'm new to the forum--and I'm not sure if you all already know about this website, but I just ran across it today. For those that don't know--and are looking for drilled / slotted rotors for your Bonnevilles and/or Auroras, heres a site called: www.KVRPerformance.com
Prices start at about $98 USD with cadmium plating available and color choices of gold, silver, and black (according to the site selections). They also have carbon fiber brake pads, and steel braided brake lines. They're located in Ottawa, Ontario. Just a little something for those that are interested.
