This page describes my thoughts on customizing cars, focusing on two interfaces that I, Rikutsu-Kone-Taro, pay attention to first, as well as my thoughts on the GR-DAT specification 2024 model GR Yaris.
Please note that the following content reflects my subjective opinion, filled with my usual arbitrary and biased views, so please proceed with that in mind.
Though I attempted to use Rikutsu-Kone-Taro’s style of expression, the essence boils down to the driver position and suspension.
As a premise, I must confess I’m an amateur driver. For an amateur driver to handle a car proficiently, improving the interface between the driver and the car should be the first point of focus.
In other words, customizing aspects such as the seat, shifter, and steering wheel surroundings to achieve a comfortable driving position. It would be even more appreciated if visibility could be improved (Photo 1).
Simultaneously, attention should also be paid to improving the interface between the car and the road surface, namely, the suspension. This includes aspects such as tires, wheels, spring rates, shock absorber damping, and alignment.
Fortunately, the GR Yaris RZHP had a reasonably decent car-to-road interface right out of the factory, so I could concentrate on the driver-to-car interface.
Regarding the car-to-road interface, recently, I installed adjustable suspension both front and rear (Photo 2 & 3).
So, the customization of Rikutsu-Kone-Taro’s GR Yaris RZHP reached a level that passed inspection and achieved a certain level of completion (Click here for details).
Now, I’m pumped up and ready to enjoy driving it to the fullest.
But then, right at that moment, the GR Yaris received a minor update announcement, which included significant improvements in the driver-to-car interface, such as redesigning the dashboard and lowering the seat position (Photo 4).
Furthermore, the car itself has been upgraded by approximately 10% in engine power compared to the 2020 model GR Yaris, and the strength of the chassis and shock absorber mounting points has been increased. Additionally, a high-speed multi-stage automatic transmission specification called GR-DAT has been added (Photo 5).
