Hawk HP+ Brake Pads: Hawk HP+ Subaru WRX brake pads use a race compound designed to take the abuse of track driving and meet the demands of street driving as well. Designed for street cars that make it to the track once in a while (such as Autocrossers, Solo II, etc.) these pads have increased friction over the HPS, are a little noisier and dustier, but have a much tougher grip.

These pads are REALLY squeaky I highly recommend not to use, if u drive your car everyday. Had to get another brand of pads they didnt even last a week on my car.
