They went through the effort to hire a bearing engineer to help them design a workable product, tested it repeatedly in running engines, and then modified or replace various components before bringing the final product to market. The result is a well designed replacement bearing whose shear number of successful installations speaks for itself.
And people still try to find a cheap way out by experimenting with unknown and unproven bearings at the risk of a very expensive engine, all in the hope of saving a couple of bucks. Sorry. but I just do not understand this.

When the bearing part itself is only a small part of the total cost.
You could have added the failures LN/Flat6 went through with off the shelf items and even one of their early designs had to be redone after the first dozens were out there and they got some more experience on them. But forum posters think that specs are everything and trumpet their "success" after a few miles. I hope they don't have as many failed test engines as LN/Flat6 did before they got it right.
Another difference is the kit contains other improved parts beyond the bearing itself. From flange to bolts to seals to ....
You put a new IMS in to reduce risk.
Recall how many test mules Porsche had and they still got it wrong several times.
