From Apex's marketing pages:

As of the date this article was posted, Titan 7 advertises that their wheels are “durability tested according to DOT / SAE and JWL / VIA standards” and BimmerWorld claims their wheels are “tested above JWL standards and VIA certified”. Both companies have the VIA logo machined directly into their wheels even though they haven’t been tested or registered by the VIA. We’ve been monitoring the database, and their wheels have never shown up despite the release of numerous wheel fitments over the past few years. Even if Titan 7 applied to register all of its wheels today, the VIA would reject some of them. We’ve confirmed that not all of Titan 7’s fitments meet the minimum JWL requirements, which is a prerequisite of the VIA approval. You can read more about that in our write-up on JWL testing.

We bought one of Titan 7’s wheels so we could see it for ourselves and compare its brake clearances to those of our own wheels. That’s when we noticed the serious discrepancy. The JWL requirement for 18” wheels with a 5×130 bolt pattern is a load rating of 735 kg (1,620 lb.). The Titan 7 wheel is marked as being rated to only 690 kg (1,521 lb.). That’s approximately 100 lb. less per corner, or 400 lb. less per car, than the minimum JWL required load rating. If that wheel has been fully weight-optimized to the 690 kg load rating as alluded to in their marketing, then reengineering and adding extra material (and thus weight) is almost certainly required to avoid cracking during the dynamic cornering fatigue test (bending test).
