Rusty is Right.
Had this happen on my last KH set up. You’d have to machine quite a lot though, it’s my estimation that at least 1/16 or up to 3/32 (60 -100 thou) material would need the removed In an a very narrow band. Well maybe thats not too much? Not sure how much material is available in the ‘’hat’ area but will be looking now when my new cheap rotors arrive as I bought a pair to put on the shelf for future use.
one pic is a hit blurry. Sorry
