SLOT88RESMI: Peripheral Component Interconnect

SLOT88RESMI Packard had its excellent four-wheel "Torsion Level" system for 1955-56, so the idea wasn't really new.

Instead of sending road shock into the chassis or body like coil or leaf springs, torsion bars absorbed most of it by twisting against their mounts.|Joel Gascoigne and Leo Widrich
