It was super delayed and I think that's because they couldn't execute in all the ways they promised they would. The final product is very rushed and pretty different from the initial promises. I think they got into "Let's just ship SOMETHING" mode as the delays were getting insane.
I can't find pictures online but I'm assuming since it only affects the 2wd and it says if the rotor cracks the stud might leave that the rotor is also the hub.
Doing a half baked job on a part for your super low volume "we only make this to advertise a low starting price" model is something just about any OEM would do.
I bet their supplier just took whatever Chevy Van rotor they had that was close and modified it to fit and as a result it got a little thin somewhere.
Edit: Nope, I couldn't find a picture but I found pictures of big brake kits for the 2wd and clearly it's not an old (read: cheap) integrated hub and rotor.
