Front Wheel Shimmy trouble shooting.

[mvk24_imp]

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?

I got cheap ones from China and they were not machined right and wouldn't even line up with the mounts (learned my lesson)

So I got the TRWs from France I believe. Worked great and front brake shimmy/pulsing went away. When I tested/measured the rotors I couldn't not find the warp at all but when I swapped to the new ones it stopped so it must have been a very subtle warp still caused the problem.

Think I ended up sourcing them from a different website but I see them on ebay also like above.
