yes, although the schroth belts are usually 2" wide instead
BTW, it also helps if you have some recline in the seat, although
you shouldn't sacrifice your leverage on the steering wheel.

i don't think it's that bad. it doesn't take very long to install
and remove the bar during your track prep. remove two bolts, install
bar, replace bolts. i agree it's a little more work than simply
connecting the schroth belts to the rear seatbelt buckles.

i've heard of people who suffered soft tissue injuries and back
injuries after accidents with schroth harnesses. however, no
hard data saying they would've been better off with the stock
belts. some people did sustain injuries from submarining under
the belts, which an antisubmarine strap would have prevented.

yeah, i wouldn't mount a race harness in the manner i described
first. some people do. i'd use the bar between the b-pillars.

ok. i don't see the installation of a race harness as being
substantially more difficult than a schroth, and maybe that's
where we differ.

sorry, javad, not trying to antagonize you. the very fact that

yes, i understand. but again, having installed several proper
harnesses in daily-driven cars, i don't think they're all that
much more impractical or difficult to use than the schroth, and
we both agree that they're safer.
hopefully, none of us here will ever have to find out firsthand
how good the belts are.
