Thats a great help thanks, very deceiving as the 2 lugs line up perfectly with the hall sensors!it is a normal PAS magnet disk and since so many brocken motor at the dealers I guess you can buy this disk at any serious BBS seller in the uk
The two magnetic lugs that you mentioned are actually just to melt the magnetring solid to the e plastic disk
btw, this are not two magnets the ring is the magnet with 24 pole if I remember correctly about the 24 or 32 or what ever you can see them under a special lens
