that does look rather tiny, compared to what one would expect from a vehicle capable of way more handling prowess than our rides.
could that be 13, 14, or 15mm thread instead of UNF thread size ?
i have always wondered how OEM's decide on, or test for, thread/bolt size per application, as i know about thread strength in shear applications, and always seem to want to go way more/larger than necessary so as to ensure myself the bolt/thread size will not cause problems in the application i am contemplating.
