The same thing has been happening on My Turbo MX-5.
I bought my rotors from race Brakes.
Have DBA 4000 T3, and Carbotech XP10 brake pads, and they have caused vibrations since going in.
Another guy, with same car, same rotors and same pads that I race with is having the same problem.

I have driven other MX-5's with the older 6x6 4000's and Carbotech pads on the track without an issue so I'm blaming the rotors still.
I have contacted Carbotech, but have yet to contact DBA.

I'll gladly go back to the old 6x6 Wiper slot design if I can find them anywhere still in stock.

Just one question sjako, are the QFM HPX pads a ceramic based pad?
I have only heard people complain about these rotors with ceramic based bads. These sought of pads create a transfer layer on the disc, and with this slot design, I cannot get a even layer on the disc.
My Carbotech XP10's, are a Ceramic based race pad.
