I've heard good and bad about all of the "knock off" companies...Konig, Rota, whoever. Most of the bad is on Konig's heavy "pimp" wheels, rather than their knockoffs. It seems the Feathers & Daylites are popular with Miata & Mini guys that use them for track days, too.
I've seen posts of Rays, Enkei, and others failing on the track. All companies have their good & bad.

FWIW, it seems the Daylites are made in Japan.
