The inboard Schroth shoulder belt is designed to expand on impact, making your chest pivot slightly instead of allowing your body to slide under the lap belts. Run it by Schattenbaum and RTR and see what they think.
4pt are out for Schattenbaum, regardless of ASM. RTR requires a visual inspection and signoff by the chair to ensure proper installation.
