I re-read this and want to bring this back from the dead to call bullshit (kinda). Plenty of cast wheels fail, new and old. I can bring you dozens of pictures of rotas and other wheels that have been destroyed. So it is kind of disingenuous to blame a wheel failure in a racing situation of the age of the wheel when there are plenty of examples of modern wheels doing the exact same thing. If you want a real quality wheel that you can push as hard as you want then you buy forged, not cast. And I will defend Japanese metallurgy over chinese metallurgy any day of the week. We are fans of Datsun. Look at the incredible engineering our cars had for their time. Fully independent suspension. Super beefy blocks and great head design. The Japanese culture in general has always been detail oriented and that is why they now make some of the best cars on the road today. You couldn't pay me to drive on DOT approved chinese tires. Whereas Bridgestone, Toyo, and Yokohama are all excellent tires.
