10 While we completed much of the interior in our last installment, we didn't install our passenger restraints. The kit-supplied restraints are a standard latch-link five-point restraint that works fine when used in the proper application/seating scenario. With the retro low-back buckets, this style of restraint really isn't the best option (if we had high-back racing seats with belt slots, we'd be fine). Instead, we opted to upgrade our restraints to Schroth's Profi-II FE camlocks (PNs vary by color, $255 per side) from HMS Motorsport. These belts are a four-point setup that are DOT approved for street use and don't require an anti-sub belt, which wouldn't work with our style of seat anyway. The Schroth ASM (anti-submarining) mechanism is a specially stitched fold of the inboard shoulder harness. In the event of a collision, this harness stretches at a different rate than the outboard shoulder by releasing the stitched area, which in turn allows a small amount of upper-body rotation.
