Om moderniseringarna i 4:e generationen:
A 4-link coil with a lateral rod that offers superior riding comfort and driving stability was adopted for the rear suspension. The merit of the conventional leaf spring suspension was its strength on bad roads, and this type of suspension had been used in successive Corolla models to meet the demanding road conditions throughout the world. However, an incident spurred the change to this new suspension. While Agetsuma was visiting Holland, the president of an agency showed him the leaf spring in a horse-drawn carriage and stated that the Corolla was the same as that carriage. Agetsuma later reflected on that moment and stated, "It was a major shock. But while it was difficult, we were bold enough to make the change."
In the steering system, a rack & pinion mechanism was newly adopted. Initially it was only made available on the 1.3-liter engine models, and the other models adopted the conventional ball nut type mechanism. Fumio Agetsuma explained the reason for this: "I personally liked the direct feel of the rack & pinion system and wanted to switch all the models. However, our loyal customers voiced strong opinions concerning the danger of sudden changes to the Corolla's handling characteristics, so we decided to make the switchover in stages." Approximately 75-80 percent of customers replace their Corollas with new Corollas, which is a large number. To protect those customers, sudden changes were avoided. In fact, rack & pinion steering was expanded and made available in the 1.5-liter engine models in the latter half of the model period and was adopted on all models of the fifth generation Corolla.
