Didn't you kind of imply below that you had a cure for warped?
Cure for "apparent" warp. Sometimes a bike will pulse the lever like crazy making you think the rotor is warped. It's often dirty button and/or a bad layer of brake material on the rotor. Clean the buttons and lube them just a tiny bit so the rotor can float properly and then scrub the ever loving crap out of the rotor with brake cleaner and a genuine ScotchBrite green pad to get the old, uneven brake material off the disc. Then suff up your pads and do a series of 10 hard stops from high speed with cooling between. This lays down a new, even layer of brake material on the disc and beds in the pads.
I wouldn't believe this would work but my bike shuddered like crazy when I got it, I swore I needed new rotors. I did this and it was silk smooth.
You can also beat down the button springs and make full floating rotors but that's a more aggressive strategy.
