I don’t think cooling ducts are what i need. I’m just looking for a good replacement rotor. Seems that when I use lower end rotors I always get the vibration back after a few months. During my search I happened to come across these and wanted to see if anyone has used them.
I have flushed the fluid a few times, I use Hawk HPS pads and stopping isn’t a problem. I only drive a grandprix so its not like I would be tracking the car besides running the 1/4 once in a while.
