ACG brake pads vs. stock

So I finally got my Porterfield Carbon/Kevlar pads from ACG put on the car, and the difference is pretty good so far. I want to caveat this by saying that I use the car as a daily driver, and can’t speak to their performance in track conditions. Also, I have only had them on the car for about 150 miles, so I can’t say what the long term results will look like. Having said that, I am not embarrassed anymore when stopping. It no longer sounds like a school bus coming to a stop, yay! I can't tell a difference between the stopping power of these pads versus the stock ones either.

In regards to brake dust, its still there, but no where near as bad as the stock pads. Below are two videos that I made. The first one is on the stock pads, wheels washed, and with 100 miles of driving. The second video is the same conditions, but on the ACG pads.
