Radial tuned suspension
From Holdenpaedia
In 1977 with the introduction of the LX range, improvements were subtle but showed drastic improvements in performance. It takes a trained eye to compare a "76" and "77" LX, Radial tuned suspension not only included Steel belted tyres, and revised coils, shocks and bushes. The pivot points for both upper and lower suspension arms were relocated. HZ RT is more notticeable, the upper mounts are welded further back on the chasis. They set a half degree of negative camber (at rest) to the front wheels. The revised control arms allowed extra camber. Which increased with the body on roll to 3 percent. The steering ratio was dropped from 18.0 to 20.4 to reduce effort.
