I recently switched to Hawk 5.0 pads (front only so far) because of what I've read about them.
I'll just say, in my experience, they're not quite as confidence inspiring as the stock pads. I may switch back to stock at some point if the muriatic acid ends up being a good way to keep my wheels clean of caked-on dust.
They took a long time to break in on my stock rotors, which was quite alarming initially. I did multiple break-in sessions before they felt right. Probably 3-4 brake ins in a local parking lot over the course of 2 weeks, along with the local and highway driving in-between.
Now, they feel good, but not great like the stock pads. Much less initial bite, which may be okay, though I'm worried it increases my braking distance. The overall grip seems comparable, but a little less grippy. I haven't done any insane braking to check the fade. Wish I could hop in a FiST with stock pads again and give it another go to compare now that I've tried these.
