FYI, if you have nothing there at all - you need to put this one on.

one from RS car is more efficient but costs $200+. this one above is just $49.

but you can mount them both if you keep overheating rear calipers.

Agree with the OP that more cooling is required. Especially on the rear where PSM overworks the brakes.

I noticed that the holes on the inside of my rear rotors are plugged with break dust. Would these keep the brake dust from building up?

They're really not going to help the cross-drilled holes. Those will plug up anyway. They may help get more airflow through the vents, keeping them cleaner.

What's the brake bias front/rear?

ECS Tuning

The Turbo ducts don't move as much air as the GT2 ducts, and direct the air at the calipers. GT2 RS ducts are more effective, and direct the air at the rotor itself, providing you with superior cooling and increased air flow for your rear braking which will lead to longevity in your pads and rotors while increasing braking sustainability.
