I need some suspension advice! I bought a 914-6 track car last spring and it is very soft. I don't know what I have installed yet but I suspect I need an upgrade over the winter. The car is a 2.8 liter with full cage. Any recommendations as to torsion bar size and rear springs? The car has front and rear sway bars, Bilsteins and monoball
front mounts. (IMG:style_emoticons/default/beer3.gif) (IMG:style_emoticons/default/smash.gif) |

The front and rear of the 914 have different motion ratios. In simple terms, the motion ratio is a way to express what spring rate the tire on the track "sees" when taking into account the angles, attachment points, and "leverage" the suspension applies to the spring or torsion bar. An example would be if the rear suspension has a motion ratio of 1.0, and the front .90. If you had 200# rear springs, the fronts would need to be 180# to have matching "wheel rates" front to rear.
180/90=2.0. 200/100=2.0. |
