GG54172 Posted March 11, 2009 Share #1 Posted March 11, 2009 I am working on a "science project" in my garage this summer. I need two matching steel brake rotors from a motorcycle. Larger diameter would certainly be better. My only requirement is that rotors must be of some material where a magnet will stick to it. Used and abused is fine. Cheaper is better. If someone has a couple of scrap rotors in their garage, I'd like to make an offer. If you must know, I am trying to make a small scale eddy current dynamometer. I want to compare the "performance" of thin motorcycle rotors to the ford mustang rotors I am currently using. Link to comment Share on other sites More sharing options...
pegscraper Posted March 11, 2009 Share #2 Posted March 11, 2009 You're running Ford Mustang rotors on your bike? Never heard of that one. Did you put on the strut front suspension too? Link to comment Share on other sites More sharing options...

No, I am using mustang rotors on the dynamometer I am building. Link to comment Share on other sites More sharing options...

mountainhorsega Posted March 12, 2009 Share #5 Posted March 12, 2009 I think I have 1 rear RSTD rotor (I don't remember if we pitched it or not) - and I don't know if it's magnetic or not. I will try to look if you are still interested. Just PM me if you are. Link to comment Share on other sites More sharing options...
