Hawk HP+ pads are made for the Subaru that gets driven to and on the track. The HP+ offers increased friction over the HPS, at the price of a little more noise (squealing) and more dust. Brake squeal is not uncommon in the HP+ due to the higher temperatures required for their peak friction, but once warmed up, this higher operating temperature will consistently allow your Subaru to brake more quickly, with minimal fade. These pads are excellent for the occasional HPDE/track day or for the very competitive autocross driver.

Novice track driver here and I had confidence in these pads through all of my 20 min. sessions. Combined with Motul 5.1 fluid, brakes never faded, but as a beginner driver, I did not push my '13 STI anywhere near its limit. As usual, the pads are real noisy for daily driving, and do give out a lot of brake dust.
