Front Wheel Shimmy trouble shooting.

[JLEECB]

I got the JB Power magtan rims. They were second hand from a forum member who was selling his bike and extra parts. The rotors are my original ones. The breaking power has always been good, but it’s always had that rubbing noise that many complain about. I’ll go through old forum posts, but is there good recommendations for aftermarket rotors? I’m not concerned with price, just quality. What about brake pads since it’ll all be apart anyways?
