Have been many 10.40s and a few 10.30s in A.SA with bench seat. If harness is installed correctly / fitted and the driver actually tightly cinches himself in place it will keep you safe. Seat back should be bolted to roll bar and if not a high back seat, a properly placed and installed support for head and neck.
No seats specifically designed for drag or road racing in stock eliminator.
Build a late model car or move to super stock.
My 90 Camaro has high back seats with some lateral support.
But it does not go in the 10s and I am being chased most of the time.
