UPDATE

So, after installing the Hawk HPS 5.0 pads, I noticed heavy brake dust on my RF wheel...no dust on the others. Upon examining further, one of the pads was never radiused (they have about a 30degree flat on the leading/trailing edges of the pad). Because of this, a significant amount of additional pad surface area contacts the rotor. It also was resulting in squeaking.

I contacted Hawk about this and the reseller but received zero response.

Anyway, I reinstalled the factory pads for now. I will say that the HPS 5.0 pads are a big improvement for the street. However, until I can address the defective pad, I'm not going to reinstall them. Back to the soft, low-bite factory pads. Oh well.
