Powerstop Brakes
 

Okay, I've done a dozen searches for Powerstop, and I haven't seen much in the way of positives or negatives on these. All I want to know is:

1-Are the slotted rotors any better or worse than OEM?
2-Are the pads any better or worse than OEM?
3-Have there been any issues with warping, cracking, or excessive wear?
4-Are they a performance bargain, or are you getting what you pay for? (Which is to say, are they cheap because they suck?)

Appreciate any help anybody can offer!
