i bought 4 GD series sport EBC rotors without really researching them. they came in the mail today and had a warning about the noise that the GD series rotors make due to the dimples. i searched online and found that some people complain about the noise when they go from regular rotors to drilled/dimples. some even said they just went back to OEM because the noise was too annoying. then there were some people that said that they could barely hear anything even with the windows down and that the noise didnt bother them. and some people said they have no noise...

before i exchange them i wanted some input from anybody who has ever had drilled or dimpled rotors. i dont take my car to the track or really race or anything. i mostly just cruise around. but i do like the sportier look. whats the noise really like and should i keep them or exhange them?

 

I have the DBA drilled/slotted rotors and yes they make noise for about the first 10k miles. Since you know where the sound is coming from it's not a concern, not knowing would freak me out!.

I love the noise from rotors like that!
