since fitting my v6 brakes with grooved/drill black diamond discs i get slight brake judder at more high speeds and hard braking from speed, from say 40 and below there fine, steering wheel also judders slightly
reckon discs are warped?? does running no spigot rings make difference as my old 1600 brakes never had spgots and they never did it.

did you prep the hub and check it for flattness before fitting the discs?
i always use a stand with a push gauge mounted on it to check for run-out when fitting new discs.

did you rub them down before fitting the new discs? even the slightest bit of rust or grit can make a difference.
