I recently recieved two new 3rd gen rotors from mazda motorsports, and it looks as though they have revised them to increase the clearance on the sides similar to what I have read as race clearancing.

For some reason they didn't go all the way to the outter oil control ring journal.

Pics are here: and not getting much attention.

Check it out & I'd love to hear some feedback.
