"These calipers are known to be able to apply the most torque of any single piston caliper made to fit a BMW of the time for extreme stopping power."

How can pistons have torque?

How can pistons have torque?
That is braking torque, ie, power to reduce moving mass to rest.

The calipers just apply direct pressure to the rotors.

pistons are larger thus applying more squeeze.

Yeah, but the effect of the friction between the pads and the rotors is to produce a torque - the rotors "try" to rotate the pads with them and into the calipers; the calipers stop the pads from rotating with the rotors. Just as torque speeds you up, so it also slows you down.

it can't but it sounds cool anyway =)

Torque is angular force. the rotor aplies torque to the pad, not vice versa.
