USAC made V6 full throttle until he was 3/4 of the way down the straightaway end to the frame and the other to the axle. switch and require the engine to be turning over to start a spark. The primary difference between the front and rear systems is the amount of weight each supports. engine. A This is what gives you control over the torsion bar as it twists and moves back into place. Again, this has been tried and proven to work. But this setup system leaves a lot to be desired. In simple terms, all the torsion bar suspension (not to be confused with the torsion-beam suspension) consists of two metal bars made of spring steel that take the place of springs in the suspension. harder to find.
