Well I just purchased and installed the rotors a couple hours ago, and mainly I'm overall impressed. They look freaking awsome and the bite seems just right. One thing that's wiered is the noise it makes when I brake. I believe it is just caused by the air being pushed though the slots by the pads, but it kinda sounds like a playing card smaking bicycle spokes LOL!!! Think it's normal and its really not to loud, but anyone else hear something similar???

 

Does it only happen when the brakes are cold!? or hot as well!?

On my old corolla with uprated brakes.. used to squeal like crazy till u got the rotors super duper hot..

 

does it all the time cold or hot

 

yeah i would also like to know

 

mine make the same noise hot or cold. no worries

 

You haven't broken in your rotors yet. Pads haven't bedded into the rotors. It should go away.

 

well if put about 30 miles on them and sound is still there.

 

I always noticed a bit more noise from slotted/crossdrilled when I had them but it should only be audible when there is something to reflect the noise....like driving close to a curb, wall, etc. It sounding like a light brushing sound and was always there.

 

it's normal, i have that sound all the time, hot or cold, and it's been almost 4k miles since i got them on. but now i cant hear it because my exhaust is so loud

 

thats just how drilled and slotted rotors sound.
