The ff-1 and 1300G models have a wishbone type independent front suspension, with torsion bar mounted upper control arms. They also have inboard drum type front brakes, utilized for stress reduction on the torsion bars and weight reduction on the suspension as a whole.
In 1972, a MacPherson strut front suspension was incorporated on all GL and DL models. This system has a double action shock absorber (damper strut) located inside a coil spring, both of which are mounted on the transverse links (control arms). This eliminates the torsion bars. The transverse link (control arm) has a maintenance free ball joint riveted at the outer end, and a stabilizer bar runs from both control arms to a body mount. The advantage of using this system is in overall weight reduction and improved stability and handling.
In 1975, the MacPherson suspension system was slightly modified to include a leading rod between the transverse link and the rear crossmember. This further improved stability.
