The steel body shell added additional strength to the chassis through a construction technique developed by Rayton Fissore called "UNIVIS." The body consisted of a square tubular structure bolted to the subframe with 10 rubber mounts (Silentbloc).
The incorporation of a steel body shell into the chassis utilized a specialized technique called "UNIVIS" developed by Rayton Fissore, which involved attaching a square tubular structure to the subframe with 10 rubber mounts (Silentbloc) for enhanced rigidity and stability.
