| braking hard in my experience at high speeds isnt what makes the rotors warp... it depends on how hot the brakes get... and they warp when you brake hard (brakes heated up) then you let the car sit like in park... that lets the brakes cool un evenly because the pads and calipers are still hot so they are still heating the rotors and the rest of the rotor is cooling... you shuold roll the car back and forth with in a couple feet so that the rotor never settles in one spot at a time until the brakes cool down... also a cool down lap of barely using the brake at slower speeds is also a great way to let the air blow on the brakes and cool them...
just my 2 cents...
