These pads get great reviews, but you need to be pushing them pretty hard for a street car in order for them to not leave deposits on your rotors.

Pad deposits increase with heat, which is why you have to brake hard to bed the brakes - the heat is what causes that initial layer of pad material to be deposited on the rotor. So your comments that deposits are occurring because the rotors are "too cold" makes no sense
The common misnomer of "warped rotors" typically happens when you heat up the brakes (like in an emergency braking situation or 'riding' the brakes) and then come to a complete stop with the pads sitting in one place on the rotors. The hot pad material continues to transfer to the rotor in that one spot, creating a high point on the rotor surface which is the reason for shuddering or shaking during braking.
