A few things:

1. Rotors rarely actually warp. The phenomena that generally is to blame is brake pad deposits on the rotor face. Doing some hard braking from ~55 to 5 mph 5 or 6 times in a row and then allowing the brakes to cool without having the brakes applied at all may help.

2. Vibration at or above a certain speed with everything else being the same often indicates a wheel (or wheels) that are out of balance.

3. I like the Z1 2-piece rotors on my car but for a non-competition or HPDE car they are probably just a waste of money.
