In order to establish the relieved stability while straight running, toe direction should be fixed as much as possible in every wheel. For example, anti-rolling bar called a stabilizer set in both front and rear suspension is thought to be activated only for preventing excessive rolling change of position, but actually they play a great part of the contribution to straight running stability. I have ever experienced in XH-200 OPEL B-Vectra after replacing the worn front stabilizer links on both side those had ignorable backlashes in ball joints. After the periodical maintenance, the stability while straight running had been remarkably improver like some different car. Because the wear progress goes gradually, the driver has difficulty to perceive any inconvenience like that. Any way, as I have such kind of experience in the past, applied I the same method on SXE10 TOYOTA Altezza that has some problem in straight running stability mainly because of innate too much suspension compliance, soft and movable bush rubber hardness. In order to fix and tighten the stabilizer bars, front and rear, small pieces of 1mm thickness rubber were applied on stabilizer bush bracket portions promptly. This tiny and trifle modification changes compliance so much. The torsion bar stabilizers F/R had not been activated in the very beginning stage of suspension vertical movement under the loose clumping by the stabilizer bushes condition. As a conclusion, this experimental trial was nothing but "Bingo!". The steering response character resembles BMW 3 normal models.
Now, I have been fully contented in this Altezza. With all component of this car, reliable and unbreakable 3SGE latest sophisticated motor with excellent control, AISHIN smooth 5 speed automatic trans-axle and double wishborn suspension construction on 4 wheels do not give me any reasons to deny Altezza. Probably, I suppose this car will continue till I go.
