I have been running Hawk HP+'s for awhile. I absolutely love how they bite and they have had zero issues on the track or mountain runs. However, they dust like a damn blizzard and are squeaky as hell. The running joke was I had was that I after I washed my car...just pulling out of the driveway would get my wheels dirty. To make matters worse, the dust is brown so it even really showed up on my flat black wheels.
After dealing with this for awhile, I finally decided to run a DD set of pads and a track/mountain run set of pads. Since it basically takes 20 minutes or less to swap pads on Brembo's including jacking the car up, this really isn't that big of a deal.
I searched around the internet to find a set of pads that were half way decent that didn't dust all over the wheels. After seeing some reviews on TireRack.com and IWSTI, I landed on the Posi Quiets.
As the name implies, they are QUIET! They also do not get the wheels dirty...and they are pretty cheap. They aren't Autozone brand cheap but a lot cheaper than the track pads. The braking bite is not as good as the HP+'s but I was expecting that. They are find for daily driving use and that is all that really matters for their purpose.
We'll see how they do over time, but so far I am liking the different pads for different purposes setup.
