Why are they mixing inches and mm?
#1

This goes for most manufacturers of upgrade kits for our cars.

Why mix between metrics and inches when it comes to hardware? I couldn't care less about whether to go inches or mm in general (as far as tools go I have both since my Mopar-days) but I cannot understand the reason for going with inches where possible on a car that use metric everywhere save for the fastening of the safety belts.

Is there an obvious reason for this?

that's a DOT thing - they require that all safety hardware meet very specific SAE standards as a part of a standardized program

Aren't metric hardware DOT-approved?

not when it comes to safety stuff - they are still stuck on that one

interesting side note: even american cars which had since gone metric still had SAE seat belt bolts - i'm not sure they have changed that even now
