It's not unheard of to get brake judder caused by uneven disks. A colleague had new disks (rather expensive ones) fitted to his Evo and couldn't figure out why they were causing judder. The solution was to have the disks very lightly skimmed. It only takes a tiny amount of warp to cause a lot of judder. Now the truth is that if you're spending £300+ on a pair of new disks, you would expect them to to be perfect straight out of the box and not to have to faff about getting them skimmed.
I'd return your disks to the supplier and get them to refund or replace with a pair which aren't warped.
More likely they were incorrectly fitted, hubs not properly cleaned.
Don't know. The one's I hat that problem with had a measurable variation in thickness, as though the faces had been machined separately, with the disk turned round between - that was the suggestion from the guy who measured them, Nick Dixon at MND Motorsport. I remember he was appalled at how bad they were. But, at the time, in the 1980s, it was cheaper to skim them than buy from a more reputable factor.
