I'd guess there's a pretty good chance none of us are physicists so deciding whether the studs have a higher or lower shear capacity than the fiber glass floor's ability to withstand the studs trying to rip themselves out first is really just food for conversation. The Delorean seat belts are anchored independent of the seat itself and hopefully would reign in the load in the event of a frontal crash. There isn't much room for the seat to go backward in a rear end crash. With that in mind I'm still comfortable adjusting the seat, with-in reason, by using washers for shims.
