So I guess your rotors are running true and pretty much straight as they're new?

If it's a really bad pulsating/judder that gets faster the faster you go then it's could be down to partial contamination on one section of the rotor so pads are grabbing like they should and then not as the contaminated section passes through.

If it's one of those rotors with the larger or unevenly spaced holes and wavy edges (usually to try to shave grams or look cool) sometimes they'll pulse as more/less rotor material is in contact with the pads. Something like the one below? Or the pad could be too high/low and not on the brake track.
