I have axxis ultimates, and they seemed to be a little oversized at first. When installed, they would very gently rub the rotor w/o the brake applied. After about a week, they wore down a little and there was no problem. The braking is :thumbup: good and strong, but still as smooth as OEM.

I dunno about power slots, but I notice my brembo slotted rotors make some funny noises :dunno: Everything works very well togeher tho.

Next time, I think I'll go with blank rotors. I really only got the slots because they look more than anything. Blanks probably brake just as well unless youre on a road course.
