I have ordered this basket, from my experience in engineering I could probably do some testing to determine wear characteristics, however, I'm looking at it from a mechanic's perspective; everyone replaces the fibers / disks first, I find it unlikely that the fiber ears will fail before the clutch surface itself. Also, the basket is the most expensive item, I would prefer it to outlive the disks by a large factor. I could do some hardness testing on the fiber ears and compare it to the the plates on the basket. I'll let you guys know if i do.
