I've got a 2004 Rx8 and just recently purcashed power slot rotors for the front the are a little smaller then the factory rotors and make a fairly loud scraping noise as i drive i have the sport suspension and that's what they said they ordered. any ideas this is my first pair of power slots is the noise normal?

 

is this under braking ? there could be some slight noise as the pad rests on it but you have to be next to the wheel to hear that. also check the airduct / shield to make sure it isnt rubbing.
