IMPROVEMENTS to body rigidity, suspension design and the standard fitment of rear disc brakes and an ABS system point to relatively strong active safety characteristics in the SP20. The front occupants are provided with an airbag, seatbelt webbing clamps and pretensioners. The front seatbelts are also height adjustable to properly fit a wide range of people. The 323 has a rigid triple H structure (frames on the roof, body sides and floor structure) for strength. Interior components are ribbed or padded to offer some protection from head injury. The centre rear seating position is the only seat not to receive a head restraint and three-point seatbelt.
