Actually those ARE Dymag hoops, HRE buys them from Dymag and installs their own centers. Mayhaps, they have/will also purchase the rights to this technology from Dymag?
On a side note, whether Dymag is in bankruptcy or not, those C/F rims are not what put them there. They have a BROAD range of wheel products for many different sectors of the automotive/motorcycle/racing spectrum. These are just one of many products they offer.
