Here is the quick release option on the ST that i was referring too. If you notice the picture, all you have to do is remove the 4 bolts on the bridge (I think you don't even need a tool for it... you can remove it by clicking on the blue button and slide the bolt out) and you have the pads out.
I really like that as it would allow me to run a very aggressive pad for the track and switch to ceramic pads (low dust) for the street as fast as switching to my street wheel/tire setup.
