Kelsey Hayes rotors
Within the last 3 years, I've bought 4 pairs of new machined hat rotors, and once mounted, all rubbed the seals. Sent 3 sets back for refund and cut the last pair down on a lathe to clear the seals.
I have two pairs of used swap meet hubs with cast hat rotors. Both pairs were on their respective cars until worn passed the thickness limit, which tells me they didn't rub the seals. I just ordered a pair of the cast hat rotors shown in your link from Rock Auto, and will replace the cast hat rotors on the pair of used hub/rotors I just got at the Cupertino meet. They'll be a spare set.
The last set of machined hat rotors I bought were from Laysons and they rubbed. I took photos and sent them to Dave Layson. He said he would do his own investigation (he mounted up a set) and after doing so, agreed that they rubbed. He refunded my money and told me he was sending all of his inventory back to his supplier for replacement or modification. I am not blaming Dave Layson for this as he is not the only vendor that has this issue, and he took care of me.
