Importance of original setting

Uncomfortable vibration with noise comes into cabin of VW 1302 Super Beetle after removing reinforced carpet on tire house portion and side shill, because of annoyance of scattering terrible odor smell by long term nourished chronic mold.

Parts unnecessary had not been applied by the factory, realizing me of the toll of removing the indispensable parts.
I must consider about the annoyance by loosing the established NVH condition.

After applying harder grease into the drive shaft's CV joint equipped in NCP10 TOYOTA Vitz, she became a faultless passenger's automobile on earth.
Motor, trans-axle, suspension design, brake system and interior atmospheric condition, I've no way to complaint on it. I admire the stuff of research and develop for this model.

As for BC7 SUBARU Legacy LSi US model, precise checking is necessary soon on steering reaction, the influence of height reduction about 35mm from original design caused unpredictable result that is not able to accept if the another improvements were recommended.

The steering resisting pressure increases on the way of turning the wheel, becomes harder and harder after passing a half way and increases the resistance exponentially.

This phenomena must be caused by the ill value of TOOT, the difference of direction of frontal wheel when the outer(or inner) wheel was twisted 20 degree.

Strange reactions were caused by the knuckle ball joint center displacement toward the upper position also the same occurred on tie rod end ball joint position upward.

There exist some 3ird party's special parts supply, I cannot rely on the reliability of their parts at all, because the experiment for researching and developing had not been performed enough like an automobile maker company's ones.

The shortest way to recover this kind of inconvenience on steering action, returning to the normal and original spring if the shock absorbers may be replaced into anther ones, because the final vehicle's height is decided mainly by the compressed coil spring length, hi pressure gas shock sometimes rise up a little occasionally.

BF8's, BP57's, BD5's and BF3's sets are at hand now, I must select best one sooner or later, as a favorable, interesting and joyful task in future.
