So, the concensus is leave out the springs when using the o-ring pistons?
Even with the springs fitted, rotor runout will still push the pads away from the rotors but the springs will push them back towards the rotors again. From what I understand, this constant back and forth motion can cause air to be pumped IN to the fluid....The springs maintain the pad contact with the rotor; with out the springs, any rotor runout could push the pads away from the rotors...

Just what I read...
I've read the same thing but lip seals seem to be more sensitive to this problem, the O-rings seem to be able to handle the 'pumping' motion of the piston better... still I don't see how it would be a huge difference, if your rotor runout is perfect you'll have always contact between the pad and the rotor which translates into heat... maybe it's a good thing to have the pad .004" or so off the rotor....
