Just installed Slotted/dimpled rotors from Adam@SPP with Porterfield pads (R-4)and noticing some noises coming from the front lately.

Whenever the car goes above 35/40mph, i hear sort of like scratching(like i have something draggin underneath the car) coming from the front. I think its from both sides. THe noise will get alittle louder when i apply the brakes but it will go away once I am going less than 25mph.

I am not sure if they need to be bedded longer or if there is some major issue with it.

Does anyone has any experience with what I am describing?

Thx
