Tons of black dust? Raybestos

My experience you have to match the pads with the rotors.
I used cermic pads and slotted rotors on my 2012 Challenger R/T, it stopped it alot quicker than the factory brakes.

Put standard rotors and ceramic brakes on my old jeep wrangler, within a few thousand miles you could not stop the jeep, it was as bad as my old willys with 9" drums all the way around.

The ceramic pads on the wrangler polished the rotors ultra smooth, resulting in no stopping power from the front brakes.
