Important rear axle

The steering stability on VW 1302 Super Beetle during both in straight running and in turning curve has remarkably improved as to be leveled with recent automobiles, especially over steering phase is easy to produce by throttle controlling leading to comfortable cruising. This marvelous change was brought only by some modification on the rear trailing arm inner bush to preventing lateral displacement of trailing arm and rear axle construction. We might pay attention to only on frontal steering linkage and it supporting construction when any inconvenience are found on steering reaction, but remember here that the rear axle construction especially to lateral direction has most to do with some strange and bad feeling phenomena. The signal in-put on steering wheel is consumed by the lateral displacement of deformable rear axle construction, this is why the dull,muddy and sticky are perceived by the driver as no action with dead band, initial rising stage has no action till coming to surrender of deformable bushes finish in the construction. So, the prevention of lateral displacement of rear axle construction is very important to establish some astringent steering reaction.
I must make it clear that my intention to modify my Beetle is not arrange the original condition to pull up potentials, but re-acquire the performance of original design, because I love and admire the VW engineer's concepts 40 years ago, if they might have gone.

By the way, recent A segment smaller and low price passenger cars invite torsion beam axle, so they have disadvantages on this point, because their rear axles are so made to distort innately. This opinion is based on my actual experiments tried on EP82 TOYOTA Starlet and BLE SUBARU B4 3L model, though the axle constructions are different, former was rigid and the latter was independent promptly, the results were exactly the same, too much compliance resisting lateral force invited dull steering reactions. The attempt also on Super Beetle has carried out and established the same result as usual. Even small piece of rubber sheets could have brought a great achievement on 40 years VW 1302 Super Beetle.
